                                     PART I
 
ITEM 1. BUSINESS.
 
     MascoTech, Inc. is a leading supplier of metalworked and aftermarket
products for the transportation industry. Sophisticated technology plays a
significant role in the Company's businesses and in the design, engineering and
manufacturing of many of its products. Products are manufactured utilizing a
variety of metalworking and other process technologies. Although published
industry statistics are not available, the Company believes that it is a leading
independent producer of many of the component parts that it produces using cold,
warm or hot forming processes.
 
     MascoTech was incorporated under the laws of Delaware in 1984 as a
wholly-owned subsidiary of Masco Corporation, which in May, 1984 transferred to
MascoTech its industrial businesses. The Company became a separate public
company in July, 1984 when Masco Corporation distributed shares of Company
Common Stock as a special dividend to its stockholders. In late 1996, the
Company purchased from Masco Corporation 17 million shares of Company Common
Stock and warrants to acquire 10 million shares of Company Common Stock, thereby
reducing Masco Corporation's equity ownership from approximately 45 percent to
approximately 21 percent of the Company's outstanding Common Stock.
 
     In June, 1993, the Company changed its name to MascoTech, Inc. from Masco
Industries, Inc. to reflect the significance of technology in the design,
engineering and manufacturing of many of the Company's products and services.
Except as the context otherwise indicates, the terms "MascoTech" and the
"Company" refer to MascoTech, Inc. and its consolidated subsidiaries.
 
     During the last decade, MascoTech pursued diversified growth in the
transportation-related, architectural and defense markets. Structural changes in
recent years in the markets served by the Company, combined with the growth
opportunities and the capital requirements of certain of the Company's
Transportation-Related businesses, led the Company to an evaluation of the
prospects for all its businesses. This evaluation resulted in the Company's
strategic plan to focus on its core operating capabilities and divest certain
other businesses. The Company's engine and drivetrain group and aftermarket
group constitute the Company's core operating businesses.
 
     In late 1994, the Company adopted a plan to dispose of its architectural
products, defense and certain of its Transportation-Related businesses. The
disposition of these businesses was completed in 1996. In addition, in 1996, the
Company disposed of its heavy-gauge stamping operations and in early 1997, the
Company completed the sale of its engineering and technical services businesses
to MSX International, Inc. As part of that transaction, the Company purchased an
approximate 45 percent common equity interest in MSX International, Inc. See
"Equity Investments -- Other Equity Investments," elsewhere in Item 1 of this
Report. The cash portion of the proceeds from the disposition of these
businesses has been applied to reduce the Company's indebtedness and to provide
capital to invest in its core businesses. The disposition of these businesses
did not meet the criteria for discontinued operations treatment for accounting
purposes; accordingly, the sales and results of operations of these businesses
are included in the results of continuing operations through the date of
disposition. Businesses held for sale or sold, including the engineering and
technical services businesses and the heavy-gauge stamping operations, had sales
of approximately $412 million in 1996. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations -- Disposition of Non-Core
Businesses," included in Item 7 of this Report.

</TABLE>
 
     Net sales include the sales of businesses held for sale or sold, including
the engineering and technical services businesses and heavy-gauge stamping
operations, of approximately $412 million in 1996, $874 million in 1995 and $964
million in 1994. Additional financial information concerning the Company's
operations by industry segments as of and for the three years ended December 31,
1996 is set forth in the Note to the Company's Consolidated Financial Statements
captioned "Segment Information," included in Item 8 of this Report.
 
(1) Results exclude the energy segment which is treated as discontinued
    operations. See the Note to the Company's Consolidated Financial Statements
    captioned "Dispositions of Operations," included in Item 8 of this Report.
 
(2) Amounts are before general corporate expense.
 
(3) Includes a $32 million pre-tax loss principally from the sale of MascoTech
    Stamping Technologies, Inc. This charge impacted the Company's
    Transportation-Related Products industry segment.
 
(4) Includes $25 million in net gains resulting from sales of non-core
    businesses. These net gains were substantially offset by reductions in the
    estimated proceeds the Company expected to receive from businesses to be
    sold, aggregating $12 million, and by certain exit costs incurred in 1995
    aggregating approximately $8 million. The net gains (charge) impacts the
    Company's industry segments as follows: Transportation-Related Products --
    $21 million and Specialty Products -- $(2) million. The remaining $(14)
    million of the net gains (charge) was allocated to General Corporate
    Expense, which is not included above.
 
(5) Includes the impact of a pre-tax charge of $400 million for the disposition
    of businesses. The charge impacts the Company's industry segments for 1994
    as follows: Transportation-Related Products -- $196 million and Specialty
    Products -- $191 million. The remaining $13 million of the charge was
    allocated to General Corporate Expense, which is not included above.
 
     The Company manufactures a broad range of semi-finished components,
subassemblies and assembled products for the original equipment and aftermarket
segments of the global transportation industry. Transportation-Related Products
represented approximately 90 percent of 1996 sales. The Company provides
components and products for which reliability, quality and certainty of supply
are major factors in customers' selection of suppliers.
 
     The Company's Transportation-Related businesses manufacture engine,
drivetrain and aftermarket products. Engine and drivetrain products include
semi-finished transmission shafts, drive gears, engine
 
                                        3
<PAGE>   5
 
connecting rods, wheel spindles and front wheel drive components. Aftermarket
products include fuel and emission systems components, windshield wiper blades,
constant-velocity joints, brake hardware repair kits and other automotive
accessories.
 
     The Company's metalworked products are manufactured using various process
technologies, including cold, warm and hot forming, powdered metal forming,
value-added machining, tubular steel fabricating and hydroforming. Approximately
50 percent of the Company's 1996 sales of Transportation-Related Products
(including businesses held for disposition) resulted from sales of products made
using cold, warm or hot metal forming technologies. The Company believes that
its metalworking technologies provide cost-competitive, high-performance,
quality components required to meet the increasing demands of the automotive and
truck markets it serves.
 
     Approximately 80 percent of the Company's Transportation-Related Products
sales in 1996 (including businesses held for disposition) were original
equipment automotive products and services. Sales to original equipment
manufacturers are made through factory sales personnel and independent sales
representatives. During 1996, sales to various divisions and subsidiaries of
Ford Motor Company, Chrysler Corporation, General Motors Corporation and New
Venture Gear, Inc. accounted for approximately 18 percent, 11 percent, 10
percent and 12 percent, respectively, of the Company's net sales (including
businesses held for disposition). Sales to the automotive aftermarket are made
primarily to distributors utilizing factory sales personnel. Aftermarket
products are sold to companies distributing into the traditional, retail and
heavy duty segments of the automotive aftermarket.
 
     The disposition of the Company's Specialty Products businesses was complete
at December 31, 1996. Since the disposition of these businesses did not meet the
criteria for discontinued operations treatment for accounting purposes, sales
and results of operations for these businesses are included in the Company's
continuing operations through the dates of disposition.
 
GENERAL INFORMATION CONCERNING INDUSTRY SEGMENTS
 
     No material portion of the Company's business is seasonal or has special
working capital requirements. The Company does not consider backlog orders to be
a material factor in its industry segments. Except as noted above under
"Industry Segments," no material portion of its business is dependent upon any
one customer or subject to renegotiation of profits or termination of contracts
at the election of the federal government. Compliance with federal, state and
local regulations relating to the discharge of materials into the environment,
or otherwise relating to the protection of the environment, is not expected to
result in material capital expenditures by the Company or to have a material
effect on the Company's earnings or competitive position. See, however, "Legal
Proceedings," included as Item 3 of this Report, for a discussion of certain
pending proceedings concerning environmental matters. In general, raw materials
required by the Company are obtainable from various sources and in the
quantities desired.
 
INTERNATIONAL OPERATIONS
 
     The Company, through its subsidiaries, has businesses located in Germany,
Italy, England and the Czech Republic. Products manufactured by the Company
outside of the United States include forged automotive component parts and
constant-velocity joints. In early 1997, the Company acquired Neumeyer
Fliesspressen GmbH, a manufacturer of extruded products. See the Note to the
Company's Consolidated Financial Statements captioned "Segment Information,"
included in Item 8 of this Report for a discussion of the Company's foreign
operations and export sales.
 
     The Company's foreign operations are subject to political, monetary,
economic and other risks attendant generally to international businesses. These
risks generally vary from country to country.

PATENTS AND TRADEMARKS
 
     The Company holds a number of patents, patent applications, licenses,
trademarks and trade names. The Company considers its patents, patent

would have a material adverse effect on the Company's industry segments or on
its present business as a whole.
 
COMPETITION
 
     The major domestic and foreign markets for the Company's products are
highly competitive. Competition is based primarily on price, product engineering
and performance, technology, quality and overall customer service, with the
relative importance of such factors varying among products. The Company's global
competitors include a large number of other well-established independent
manufacturers as well as certain customers who have their own internal

ITEM 3. LEGAL PROCEEDINGS.
 
     A civil suit was filed in the United States District Court for the Central
District of California in April, 1983 by the United States of America and the
State of California against over 30 defendants, including the Company's NI
Industries, Inc. subsidiary ("NI"), for alleged release into the environment of
hazardous waste disposed of at the Stringfellow Disposal Site in California. The
plaintiffs have requested, among other things, that the defendants clean up the
contamination at that site. A consent decree has been entered into by the
plaintiffs and the defendants, including NI, providing that the consenting
parties perform partial remediation at the site. Another civil suit was filed in
the United States District Court for the Central District of California in
December, 1988 by the United States of America and the State of California
against more than 180 defendants, including NI, for alleged release into the
environment of hazardous waste disposed of at the Operating Industries, Inc.
site in California. This site served for many years as a depository for
municipal and industrial waste. The plaintiffs have requested, among other
things, that the defendants clean up the contamination at that site. Two partial
consent decrees have been entered into by the plaintiffs and a group of the
defendants, including NI, providing that the consenting parties perform certain
interim remedial work at the site and reimburse the plaintiffs for certain past
costs incurred by the plaintiffs at the site. Based upon its present knowledge
and subject to future legal and factual developments, the Company does not
believe that any of this litigation will have a material adverse effect on its
consolidated financial position, results of operations or cash flow.

* Prior to the First Quarter of 1995, dividends were paid in the quarter
  following declaration. Thereafter, dividends have been paid in the same
  quarter as declared. Consequently, although no dividend was declared during
  the First Quarter of 1995, a dividend of $.03 per share was paid during the
  period that had been declared in the Fourth Quarter of 1994.
 
     Future declarations of dividends on the Company's Common Stock are
discretionary with the Board of Directors and will depend upon the Company's
earnings, capital requirements, financial condition and other factors. Dividends
may not be paid on Company Common Stock if there are any dividend arrearages on
the Company's outstanding Preferred Stock. In addition, certain of the Company's
long-term debt instruments contain provisions that restrict the dividends that
it may pay on its capital stock. See the discussion under "Management's
Discussion and Analysis of Financial Condition and Results of Operations --
Financial Position and Liquidity," included in Item 7 of this Report and the
Note to the Company's Consolidated Financial Statements captioned "Long-Term
Debt," included in Item 8 of this Report.
 
     On February 28, 1997, there were approximately 3,900 holders of record of

     Results for 1994 include a pre-tax charge of $400 million ($315 million
after-tax or $5.35 per common share), reflecting the estimated loss on the
planned disposition of a number of the Company's businesses. See the Note to the
Company's Consolidated Financial Statements captioned "Dispositions of

     Results for 1994 are before the effect of a gain aggregating approximately
$18 million pre-tax ($11.7 million after-tax or $.20 per common share) related
to the partial reversal of the charge established in 1993 for the disposition of
the Company's energy segment. See the Note to the Company's Consolidated

to the early extinguishment of convertible debt.
 
     Results for 1993 and 1992 include pre-tax income of approximately $9
million and $25 million, respectively, as a result of gains associated with the
sale of common stock through public offerings by equity affiliates and, in 1992,
a prepayment premium related to the redemption of debentures held by the
Company. This income was largely offset by costs and expenses related to
cost-reduction initiatives, the restructuring of certain operations and product
lines, adjustments to the carrying value of certain long-term assets, and other
costs and expenses.
 
     Results for 1993 were reduced by a charge of approximately $.03 per common

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS.
 
MASCOTECH
 
     Masco Corporation undertook a major corporate restructuring during 1984,
transferring its Products for Industry businesses to the Company at their
historical net book value. MascoTech became a separate public company in
mid-1984, when Masco Corporation distributed common shares of MascoTech as a
special dividend to its shareholders. At December 31, 1996, Masco Corporation
owned approximately 21 percent of MascoTech common stock outstanding.
 
     In 1993, the Company changed its name to MascoTech, Inc. from Masco
Industries, Inc. to reflect the significance of technology in the design,
engineering and manufacturing of many of the Company's products and services.
 
CORPORATE DEVELOPMENT
 
     Since mid-1984, the Company has invested more than $1.5 billion in capital
expenditures and acquisitions combined to expand the Company's product and
technological positions in its industrial markets.
 
     Since late 1988, the Company has divested several businesses as part of its
long-term strategic plan to de-leverage its balance sheet and focus on its core
operating capabilities. The Company's divestiture activity included several
businesses transferred to its equity affiliate, TriMas Corporation ("TriMas"),
and in late 1993 the announcement of the Company's plan to dispose of its energy
segment. In addition, in late 1994 the Company announced the planned disposition
of a number of businesses including its architectural products, defense and
certain transportation-related products and services businesses. Also, in
separate transactions, the Company disposed of its remaining heavy-gauge
stamping operations in 1996 and its Technical Services business in January,
1997. The Company has realized cash proceeds of approximately $870 million
through January, 1997, from its divestiture activity, which have been applied to
reduce the Company's indebtedness and to fund its core businesses' expanded
capital investment programs. The Company's remaining core operations are
comprised of metalworking and aftermarket businesses.
 
     In early 1993, the Company acquired from Masco Corporation 10 million
shares of Company Common Stock, $77.5 million of the Company's 12% Exchangeable
Preferred Stock held by Masco Corporation, and Masco Corporation's holdings of
Emco Limited ("Emco") common stock and convertible debentures. In exchange,
Masco Corporation received from the Company $87.5 million in cash, $100 million
of the Company's 10% Exchangeable Preferred Stock (subsequently redeemed in
1993) and seven-year warrants to purchase 10 million shares of Company Common
Stock at $13 per share.
 
     The Company's major shareholder, Masco Corporation, had a long-standing
stated objective to simplify its corporate structure by reducing its affiliate
investments. More recently, Masco Corporation had committed to its shareholders
that Masco Corporation would reduce its investment in MascoTech to below 20
percent. Given the possible alternatives available to Masco Corporation to
accomplish this objective and the related uncertainty as to what action Masco
Corporation might take, together with the positive long-term outlook for
MascoTech, the MascoTech Board of Directors decided to address this issue by
proactively pursuing the purchase of Masco Corporation's holdings in MascoTech.
The MascoTech Board of Directors believed that purchasing and retiring a
substantial number of MascoTech shares (at a reasonable price) would help create
long-term value for the Company's shareholders.
 
     As a result, in late 1996, the Company purchased from Masco Corporation 17
million shares of MascoTech common stock and warrants to acquire 10 million
shares of MascoTech common stock, for approximately $266 million. As part of
this transaction, and given his role as Chairman of both Masco Corporation and
MascoTech, Richard Manoogian also agreed to sell to MascoTech one million shares
of MascoTech common stock at the then current market price of $13 5/8. As a
result, his seven percent ownership in MascoTech common stock remains
approximately the same after the share purchases. Although these transactions
result in the additional leverage of the Company's balance sheet in the
near-term, the Company believes that the substantial reduction in MascoTech
common shares outstanding should enhance the long-term financial returns for its
shareholders.

DISPOSITION OF NON-CORE BUSINESSES
 
     In late 1994, the Company adopted a plan to dispose, by sale or
liquidation, a number of businesses, including its architectural products,
defense and certain of its transportation-related products and services
businesses, as part of its long-term strategic plan to increase the focus on its
core operating capabilities. The disposition of these businesses did not meet
the criteria for discontinued operations treatment for accounting purposes;
accordingly, the sales and results of operations of these businesses are
included in continuing operations until disposition. Through dates of sale, such
businesses held for disposition had sales of approximately $90 million, $468
million and $637 million in 1996, 1995 and 1994, respectively, and operating
losses before gains (charge) on disposition of businesses, net of $14 million,
$11 million and $7 million in 1996, 1995 and 1994, respectively.
 
     The Company's carrying value of a number of the businesses to be disposed
exceeded the estimated proceeds expected from such dispositions. To reflect the
estimated loss on the disposition of these businesses, the Company recorded a
non-cash charge in 1994 aggregating $400 million pre-tax (approximately $315
million after-tax or $5.35 per common share) for those businesses for which a
loss was anticipated. At December 31, 1996, the Company has substantially
completed the disposition of such businesses for aggregate proceeds (including
related tax benefits) of approximately $400 million. The cash portion of these
proceeds has been applied to reduce the Company's indebtedness and for
investment in its core businesses.
 
     In May, 1996, the Company sold MascoTech Stamping Technologies, Inc.
(MSTI), a wholly owned subsidiary, to Tower Automotive, Inc. (Tower) resulting
in an after-tax loss of approximately $26 million ($.47 per common share),
including after-tax losses of approximately $1 million related to the closure of
a MSTI manufacturing facility not included in the sale. The Company received
initial consideration of approximately $80 million, consisting principally of
$55 million in cash, 785,000 shares of Tower common stock and warrants to
purchase additional Tower common stock. The Company applied the cash proceeds
(including approximately $14 million received from the subsequent sale of
600,000 shares of Tower common stock) to reduce its indebtedness. The Company
may receive additional consideration, contingent upon the future earnings of
MSTI over the next three years, which, if entirely earned, would substantially
offset the loss.
 
     In early 1997, the Company completed the sale of its Technical Services
Group ("TSG," comprised of the Company's engineering and technical business
services units) to MSX International, Inc. Also included in this transaction
were the net assets of APX International ("APX") which were acquired by the
Company in November, 1996. The sale resulted in total proceeds to the Company of
approximately $145 million, subject to certain adjustments, consisting of cash,
subordinated debentures, preferred stock and an approximate 45 percent common
equity interest in MSX International, Inc. Net proceeds to the Company will
approximate $90 million, after taking into account the purchase price for APX
and taxes payable in connection with this transaction. The excess of the
consideration received by the Company over the book value of the related net
assets has been deferred and will be recognized when cash is received.
 
     Businesses held for sale or sold, including MSTI and TSG, had sales of
approximately $412 million, $874 million and $964 million in 1996, 1995 and
1994, respectively, and operating income (losses) before gains (charge) on
disposition of businesses, net of $(13) million, $5 million and $8 million in
1996, 1995 and 1994, respectively.
 
PROFIT MARGINS
 
     Operating profit margins, excluding the charges in 1996 and 1994, and net
gains in 1995, from the disposition of businesses, were eight percent in 1996,
six percent in 1995 and seven percent in 1994. The increase in the operating
profit margin in 1996 compared with the previous two years is attributable to
the disposition of non-core businesses which had margins lower than the
Company's core operations. In addition, operating margins for the Company's core
businesses increased as a result of the reduction of launch and start-up related
costs and expenses incurred in 1995 and 1994 for new products associated with
the Company's capital expansion programs.

CASH FLOWS AND CAPITAL EXPENDITURES
 
     Net cash flows from operating activities decreased to $129 million in 1996
from $158 million in 1995. Net cash flows from operating activities in 1996 were
reduced by the increase in the Company's marketable securities portfolio.
 
     In early 1997, the Company amended its revolving credit agreement; as a
result, the amended $575 million revolving credit agreement is due 2002.
 
     Reflecting the favorable long-term prospects for MascoTech, the Company's
Board of Directors authorized in 1994 the repurchase of 10 million shares of
Company Common Stock and Convertible Preferred Stock. Pursuant to this
authorization, the Company has repurchased and retired approximately six million
shares of Company Common Stock since 1994 at a cost of approximately $75
million. In addition, in October, 1996, the Company purchased and retired 18
million shares of Company Common Stock and warrants to purchase 10 million
shares of Company Common Stock for cash and notes approximating $280 million
(see "Corporate Development" and "Shareholders' Equity" note to the Company's
Consolidated Financial Statements included in Item 8 of this Report).
 
     The Company in 1996 increased the quarterly dividend on its common stock to
$.05 per share from $.04.
 
     On March 15, 1995, the Company redeemed at maturity $233 million of its 10%
Senior Subordinated Notes utilizing its bank revolving credit agreement.
 
     In January, 1994, the Company issued, in a public offering, approximately
$345 million of 4 1/2% Convertible Subordinated Debentures due December 15,
2003. These debentures are convertible into Company Common Stock at $31 per
share. The net proceeds of approximately $337 million were used to redeem $250
million of 10 1/4% Senior Subordinated Notes on February 1, 1994 and to reduce
other indebtedness.
 
     Capital expenditures declined in 1996 to approximately $44 million from
$110 million and $115 million in 1995 and 1994, respectively. During 1995 and
1994, the Company made significant expenditures in capital programs to support
the Company's metalworking and aftermarket businesses. These expenditures for
new advanced manufacturing technologies, product line extensions and capacity
for new products were the result of the Company's belief in the favorable
long-term outlook for these businesses and to meet increased demand for certain
product programs.
 
INVENTORIES
 
     The Company's investment in inventories for its core businesses
approximated $70 million at December 31, 1996. The decline from 1995 levels is
the result of the disposition of MSTI and the reclassification of the Company's
Technical Services Group to net assets of businesses held for disposition. The
Company's continued emphasis on inventory management, utilizing Just-In-Time
(JIT) and other inventory management techniques, has contributed to higher
inventory turnover rates in recent years.
 
FINANCIAL POSITION AND LIQUIDITY
 
     Although the Company's total debt outstanding only increased by
approximately $50 million during 1996, debt as a percent of debt plus equity
increased to 82 percent at December 31, 1996 from 63 percent at December 31,
1995, primarily as a result of the common share and warrant purchase from Masco
Corporation. The application of cash proceeds from the sale of the Technical
Services Group and the potential transfer of the Company's Emco holdings to
Masco Corporation would reduce the Company's indebtedness to approximately $600
million on a pro forma basis at December 31, 1996, of which approximately $310
million is 4 1/2% Convertible Subordinated Debentures due 2003. The Company's
interest coverage ratio remains strong, and the Company expects that its ratio
of debt to total debt plus equity will improve as a result of the transactions
mentioned above, from the disposition of other financial assets and from the
operating performance of its businesses.
 
     At December 31, 1996 current assets, which aggregated approximately $394
million, were in excess of two times current liabilities. In addition, the
Company has significant financial assets, including ownership positions in the
securities of three publicly traded companies with an aggregate carrying value
of approxi-
 
                                       14
<PAGE>   16
 
mately $229 million. This compares with an aggregate quoted market value at
December 31, 1996 (which may differ from the amounts that could have been
realized upon disposition) of approximately $505 million.
 
     Additional borrowings available under the Company's amended revolving
credit agreement and otherwise, and anticipated internal cash flows are expected
to provide sufficient liquidity to fund the Company's foreseeable working
capital, capital expansion programs and other investment needs.
 
     The Company's amended revolving credit agreement contains restrictions
including maintenance of a specified level of tangible shareholders' equity, the
ratio of senior debt to earnings and the ratio of debt to equity. Under the most
restrictive of these provisions, approximately $70 million was available at
December 31, 1996 for the payment of cash dividends and the acquisition of
Company Common Stock. In addition, future cash dividends and any acquisition of
Company Common Stock and Convertible Preferred Stock could be further
accomplished with internal cash flows from operations.
 
     An equity affiliate of the Company has called for the redemption or
conversion of a convertible debt instrument in the first quarter of 1997. The
Company may recognize a gain from the change in the Company's common equity
ownership interest in the affiliate. The gain, if any, is dependent upon the
number of convertible debentures converted to common stock.
 
GENERAL FINANCIAL ANALYSIS
 
1996 VERSUS 1995
 
     Sales for 1996 declined to $1.3 billion from $1.7 billion in 1995,
reflecting the previously announced disposition of certain businesses. Sales of
the Company's metalworking and aftermarket businesses, however, increased eight
percent from 1995 to approximately $.9 billion, while sales of the Company's
businesses held for sale or sold decreased approximately 53 percent from the
comparable period in 1995 as a result of the disposition of a number of such
businesses.
 
     Income after preferred stock dividends in 1996 was $38.7 million or $.70
per common share. Results in 1996 include an after-tax loss of approximately $26
million ($.47 per common share) related to the sale of the Company's heavy-gauge
stamping operations (MSTI) which more than offset after-tax income of
approximately $11.7 million ($.21 per common share) related to the cumulative
effect of an accounting change. Income after preferred stock dividends in 1995
was $46.2 million or $.81 per common share.
 
     Operating profit in 1996 for the metalworking and aftermarket businesses,
before general corporate expense, increased to approximately $136 million from
$116 million in 1995, resulting from increased volume and the reduction of
launch and start-up costs and expenses related to the Company's capital
expansion programs. Businesses held for sale or sold (including MSTI and TSG)
had operating income (losses) before general corporate expense and gains
(charge) on disposition of businesses, net of approximately $(13) million and $5
million for 1996 and 1995, respectively.
 
     In December, 1994, the Company announced the planned disposition of a
number of businesses, including its architectural products, defense and certain
of its transportation-related products and services businesses, as part of its
long-term strategic plan to increase the focus on its core operating
capabilities. During 1995 and 1996, the Company completed the disposition of
such businesses for proceeds aggregating approximately $400 million. Net assets
of businesses held for sale decreased by approximately $167 million during 1996
as a result of the disposition of such businesses and from the reduction of
assets employed in these businesses through operating activity, asset sales and
the redeployment of certain assets. Net assets of businesses held for sale at
December 31, 1996 reflect the net assets of the Company's Technical Services
Group and APX International which were sold January 3, 1997.
 
     In 1995, the Company sold businesses in transactions which resulted in net
gains of approximately $25 million. These net gains were substantially offset by
reductions in the estimated net proceeds that the Company expected to receive
from certain businesses remaining to be sold, aggregating approximately $12
million, and by certain exit costs related to the businesses sold or held for
sale incurred in 1995 aggregating approximately $8 million.
 
                                       15
<PAGE>   17
 
     Other income (expense), net in 1996, was income of approximately $8 million
as compared with expense of approximately $9 million in 1995. Results for 1996
benefitted from reduced interest expense as proceeds from the disposition of
businesses were applied to reduce the Company's indebtedness as well as from
increased earnings from equity affiliates. Results for 1995 were impacted by
pre-tax income of approximately $5 million as a result of gains associated with
the sale of common stock through a public offering by an equity affiliate.
 
     The Company's 1996 effective tax rate differs from the statutory rate
principally because a significant portion of the loss on the sale of the
heavy-gauge stamping operations does not result in a tax benefit.
 
1995 VERSUS 1994
 
     Sales for 1995 were $1.7 billion which approximated 1994 sales. Sales of
the Company's metalworking and aftermarket businesses, however, increased nine
percent from 1994 to approximately $.8 billion, while sales of the Company's
businesses held for sale or sold decreased approximately nine percent from the
comparable period in 1994 as a result of the disposition of a number of such
businesses.
 
     Income after preferred stock dividends in 1995 was $46.2 million or $.81
per common share, compared with a loss of $3.96 per common share in 1994 which
reflects the non-cash charge of $400 million pre-tax ($315 million after-tax)
for the anticipated loss on the disposition of non-core businesses.
 
     Operating profit from continuing operations (excluding the gains (charge)
in 1995 and 1994, respectively, on disposition of businesses, net) in 1995 for
the metalworking and aftermarket businesses, before general corporate expense,
decreased by $11 million to approximately $116 million from $127 million in
1994. Although 1995 results benefitted from increased sales in our metalworking
and aftermarket businesses, operating performance was negatively impacted by
increased costs and expenses reflecting start-up costs associated with the
Company's expanded capital investment programs and increased steel costs.
Businesses held for sale or sold (including MSTI and TSG) had operating profit
before general corporate expense and gains (charge) on disposition of
businesses, net of approximately $5 million and $8 million for 1995 and 1994,
respectively.
 
     In December, 1994, the Company announced the planned disposition of a
number of businesses, including its architectural products, defense and certain
of its transportation-related products and services businesses, as part of its
long-term strategic plan to increase the focus on its core operating
capabilities. At December 31, 1995, the Company has disposed of certain of such
businesses for proceeds approximating $180 million. The Company expects that the
divestiture of the remaining businesses held for sale will be completed by
mid-1996 for additional proceeds (including related tax benefits) approximating
$220 million, of which approximately $120 million was received in January, 1996.
Net assets of businesses held for sale decreased by $212 million during 1995 as
a result of the disposition of such businesses and from the reduction of assets
employed in these businesses through operating activity, asset sales and the
redeployment of certain assets.
 
     During 1995, the Company sold businesses in transactions which resulted in
net gains of approximately $25 million. These net gains were substantially
offset by reductions in the estimated net proceeds that the Company expected to
receive from certain businesses remaining to be sold, aggregating approximately
$12 million, and by certain exit costs related to the businesses sold or held
for sale incurred in 1995 aggregating approximately $8 million.
 
     Other income (expense), net in 1995 was an expense of $9 million compared
with income of $13 million in 1994. Results for 1995 were impacted by a gain of
approximately $5 million pre-tax resulting from the issuance of common stock
through a public offering by an equity affiliate and from lower investment
income as compared with 1994. Other income, net in 1994 included gains of
approximately $17.9 million pre-tax from sales of a portion of the Company's
common stock holdings of an equity affiliate.
 
     Results for 1994 also benefitted from the partial reversal of the charge
established in 1993 for discontinued operations of approximately $11.7 million
after-tax and from an extraordinary gain of approximately $2.6 million after-tax
related to the early extinguishment of debt.

We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of MascoTech, Inc.
and subsidiaries as of December 31, 1996 and 1995, and the consolidated results
of their operations and their cash flows for each of the three years in the
period ended December 31, 1996, in conformity with generally accepted accounting
principles. In addition, in our opinion, the financial statement schedule
referred to above, when considered in relation to the basic financial statements
taken as a whole, presents fairly, in all material respects, the information
required to be included therein.
 
     As discussed in the footnotes to the consolidated financial statements,
effective January 1, 1996, the Company changed its method of accounting for the
impairment of long-lived assets and for long-lived assets to be disposed of.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
ACCOUNTING POLICIES:
 
     Principles of Consolidation. The consolidated financial statements include
the accounts of the Company and all majority-owned subsidiaries. All significant
intercompany transactions have been eliminated. Corporations that are 20 to 50
percent owned are accounted for by the equity method of accounting; ownership
less than 20 percent is accounted for on the cost basis unless the Company
exercises significant influence over the investee. Capital transactions by
equity affiliates, which change the Company's ownership interest at amounts
differing from the Company's carrying amount, are reflected in other income or
expense and the investment in affiliates account.
 
     The consolidated balance sheet at December 31, 1996 reflects the
segregation of net current and net non-current assets related to the disposition
of the Company's Technical Services Group ("TSG") and, at December 31, 1995,
reflects the segregation of assets related to the plan adopted in late 1994 to
dispose of certain businesses.
 
     The Company has a corporate services agreement with Masco Corporation,
which at December 31, 1996 owned approximately 21 percent of the Company's
Common Stock. Under the terms of the agreement, the Company pays fees to Masco
Corporation for various corporate staff support and administrative services,
research and development and facilities. Such fees, which are determined
principally as a percentage of net sales, aggregated approximately $7 million in
1996, $9 million in 1995, and $11 million in 1994.
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires the Company to make estimates and
assumptions that affect the reported amounts of assets and liabilities and the
disclosure of contingent assets and liabilities at the date of the financial
statements. Such estimates and assumptions also affect the reported amounts of
revenues and expenses during the reporting periods. Actual results may differ
from such estimates and assumptions.
 
     Cash and Cash Investments. The Company considers all highly liquid debt
instruments with an initial maturity of three months or less to be cash and cash
investments. The carrying amount reported in the balance sheet for cash and cash
investments approximates fair value.
 
     Marketable Securities. The Company's marketable equity securities holdings
are categorized as either trading or available-for-sale securities, and, as a
result, are stated at fair value. Changes in the fair value of trading
securities are recognized in earnings and the changes in the fair value of
available-for-sale securities are recorded in shareholders' equity, net of
deferred taxes.
 
     Receivables. Receivables are presented net of allowances for doubtful
accounts of approximately $2.0 million at both December 31, 1996 and 1995.
 
     Inventories. Inventories are stated at the lower of cost or net realizable
value, with cost determined principally by use of the first-in, first-out
method.
 
     Property and Equipment, Net. Property and equipment additions, including
significant betterments, are recorded at cost. Upon retirement or disposal of
property and equipment, the cost and accumulated depreciation are removed from
the accounts, and any gain or loss is included in income. Repair and maintenance
costs are charged to expense as incurred.
 
     Depreciation and Amortization. Depreciation is computed principally using
the straight-line method over the estimated useful lives of the assets. Annual
depreciation rates are as follows: buildings and land improvements, 2 1/2 to 10
percent, and machinery and equipment, 6 2/3 to 33 1/3 percent. Deferred
financing costs are amortized over the lives of the related debt securities. The
excess of cost over net assets of acquired companies is amortized using the
straight-line method over the period estimated to be benefitted, not exceeding
40 years. At each balance sheet date, management assesses whether there has been
a permanent impairment of the excess of cost over net assets of acquired
companies by comparing anticipated undiscounted

future cash flows from operating activities with the carrying amount of the
excess of cost over net assets of acquired companies. The factors considered by
management in performing this assessment include current operating results,
business prospects, market trends, potential product obsolescence, competitive
activities and other economic factors. Based on this assessment, there was no
permanent impairment related to the excess of cost over net assets of acquired
companies at December 31, 1996.
 
     At December 31, 1996 and 1995, accumulated amortization of the excess of
cost over net assets of acquired companies and patents was $29.4 million and
$42.3 million, respectively. Amortization expense was $8.5 million, $13.7
million and $22.9 million in 1996, 1995 and 1994, respectively.
 
     Income Taxes. The Company records income taxes in accordance with Statement
of Financial Accounting Standards No. 109 ("SFAS No. 109"), "Accounting for
Income Taxes." SFAS No. 109 is an asset and liability approach that requires the
recognition of deferred tax assets and liabilities for the expected future tax
consequences of events that have been recognized in the Company's financial
statements or tax returns. In estimating future tax consequences, SFAS No. 109
generally allows consideration of all expected future events other than
enactments of changes in the tax law or tax rates. A provision has not been made
for U.S. or additional foreign withholding taxes on approximately $47 million of
undistributed earnings of foreign subsidiaries as those earnings are intended to
be permanently reinvested. Generally, such earnings become subject to U.S. tax
upon the remittance of dividends and under certain other circumstances. It is
not practicable to estimate the amount of deferred tax liability on such
undistributed earnings.
 
     Earnings (Loss) Per Common Share. Primary earnings per common share are
based on the weighted average shares of common stock and common stock
equivalents outstanding (including the dilutive effect of options and warrants,
utilizing the treasury stock method) of 53.8 million and 57.1 million in 1996
and 1995, respectively. Primary loss per common share in 1994 is based on 58.9
million weighted average shares of common stock outstanding. The effect of
options and warrants on earnings per common share in 1994 would be
anti-dilutive. Primary earnings (loss) per common share are calculated on
earnings (loss) after deducting preferred stock dividends of $13.0 million in
each of 1996, 1995 and 1994.
 
     Fully diluted earnings per common share is presented only when the assumed
conversion of convertible securities is dilutive. Convertible securities did not
have a dilutive effect on earnings (loss) per common share in 1996, 1995 or
1994. Fully diluted earnings per common share is presented in 1996 due to the
utilization of the treasury stock method.
 
     In late 1996, the Company purchased from Masco Corporation 17 million
shares of MascoTech common stock and warrants to purchase 10 million shares of
MascoTech common stock. These shares and warrants have been retired. If such
retirement had taken place at the beginning of 1996, the pro forma primary and
fully diluted earnings per common and common equivalent share amounts would have
been $.78 and $.77, respectively, in 1996.
 
     Recently Issued Accounting Pronouncements. At January 1, 1996, the Company
adopted SFAS No. 121, "Accounting for the Impairment of Long-Lived Assets and
for Long-Lived Assets to Be Disposed Of," which resulted in a pre-tax gain
(because the fair value of the businesses being held for sale at January 1, 1996
exceeded the carrying value for such businesses) of $16.7 million ($11.7 million
after-tax), recorded as the cumulative effect of an accounting change. The pro
forma effect of the retroactive application of the change on the financial
statements for the years prior to 1996 has not been presented because the new
method did not have a material effect on the earnings reported for those years.
The Company adopted the disclosure requirements of SFAS No. 123, "Accounting for
Stock-Based Compensation," effective with the 1996 financial statements, and
elected to continue to measure compensation cost using the intrinsic value
method, in accordance with APB Opinion No. 25, "Accounting for Stock Issued to
Employees." Accordingly, no compensation cost for stock options has been
recognized. If compensation cost had been determined based on the estimated fair
value of options granted in 1996 and 1995, consistent with the methodology in
SFAS

No. 123, the pro forma effects on the Company's net income and income per common
share would not have been material. SFAS No. 125, "Accounting for Transfers and
Servicing of Financial Assets and Extinguishments of Liabilities," and the
American Institute of Certified Public Accountants' Statement of Position No.
96-1, "Environmental Remediation Liabilities," become effective in 1997 and will
not have a material impact on the Company's financial statements. The Company
expects that SFAS No. 128, "Earnings Per Share," will not have a material impact
on earnings per share when adopted in 1997.
 
SUPPLEMENTARY CASH FLOWS INFORMATION:
 
     Significant transactions not affecting cash were: in 1996: in addition to
cash received, approximately $25 million comprised of both common stock and
warrants (with a portion of the common stock subsequently sold for approximately
$14 million of cash), as consideration from the sale of MascoTech Stamping
Technologies, Inc.; in addition to the cash payment by the Company of $121
million, notes approximating $159 million were issued for the purchase of 18
million shares of the Company's Common Stock and warrants to purchase 10 million
shares of the Company's Common Stock (see "Shareholders' Equity" note); in 1995:
in addition to cash received, approximately $34 million comprised of both notes
receivable due from, and a 29 percent equity interest in, the acquiring company,
as consideration for a non-core business unit.
 
     Income taxes paid (refunded) were $(12) million, $11 million and $28
million in 1996, 1995 and 1994, respectively. Interest paid was $30 million, $55
million and $61 million in 1996, 1995 and 1994, respectively.
 
DISPOSITIONS OF OPERATIONS:
 
     In late 1994, the Company adopted a plan to dispose, by sale or
liquidation, a number of businesses, including its architectural products,
defense and certain of its transportation-related products and services
businesses, as part of its long-term strategic plan to increase the focus on its
core operating capabilities. Through dates of sale, the businesses held for
disposition had sales of approximately $90 million, $468 million and $637
million in 1996, 1995 and 1994, respectively, and operating losses before gains
(charge) on disposition of businesses, net of $14 million, $11 million and $7
million in 1996, 1995 and 1994, respectively. At December 31, 1996, the Company
has substantially completed the disposition of such businesses, and the
liability for accrued exit costs approximates $17 million, including
approximately $11 million related to post-employment benefits.
 
     The Company's carrying value of a number of the businesses disposed of
exceeded the estimated proceeds expected from such dispositions. To reflect the
estimated loss on the disposition of these businesses, the Company in 1994
recorded a non-cash charge aggregating $400 million pre-tax (approximately $315
million after-tax or $5.35 per common share) for those businesses for which a
loss was anticipated.
 
     During 1995, the Company divested a number of such businesses, in separate
transactions, for aggregate proceeds of approximately $180 million, which
resulted in net gains of approximately $25 million. These net gains were
substantially offset by reductions in the estimated net proceeds the Company
expected to receive from certain remaining businesses to be sold, aggregating
approximately $12 million, and by certain exit costs incurred in 1995
aggregating approximately $8 million.
 
     In May, 1996, the Company sold MascoTech Stamping Technologies, Inc.
(MSTI), a wholly owned subsidiary, to Tower Automotive, Inc. (Tower) resulting
in an after-tax loss of approximately $26 million ($.47 per common share),
including after-tax losses of approximately $1 million related to the closure of
a MSTI manufacturing facility not included in the sale. The Company received
initial consideration of approximately $80 million, consisting principally of
$55 million in cash, 785,000 shares of Tower common stock and warrants to
purchase additional Tower common stock. The Company applied the cash proceeds
(including approximately $14 million received from the subsequent sale of
600,000 shares of Tower common stock) to reduce its indebtedness. The Company
may receive additional consideration, contingent upon the future earnings of
MSTI over the next three years, which, if entirely earned, would substantially
offset the loss.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     On January 3, 1997, the Company completed the sale of its Technical
Services Group (comprised of the Company's engineering and technical business
services units) to MSX International, Inc. Also included in this transaction
were the net assets of APX International which were acquired by the Company in
November, 1996 for approximately $44 million. The sale will result in total
proceeds to the Company of approximately $145 million, subject to certain
adjustments, consisting of cash, subordinated debentures, preferred stock and an
approximate 45 percent common equity interest in MSX International, Inc. Net
proceeds to the Company will approximate $90 million, after taking into account
the purchase price for APX International and taxes payable in connection with
this transaction. The excess of the consideration received by the Company over
the book value of the related net assets has been deferred and will be
recognized when cash is received. The net assets of the Technical Services Group
and APX International are reflected on the consolidated balance sheet as net
assets of businesses held for disposition at December 31, 1996. The Company has
not reflected any revenues or expenses in the consolidated statement of
operations related to APX International from the date of acquisition through
December 31, 1996 as control was deemed to be temporary.
 
     The disposition of businesses held for sale or sold, including MSTI and
TSG, did not meet the criteria for discontinued operations treatment for
accounting purposes; accordingly, the sales and results of operations of these
businesses were included in continuing operations until disposition. Businesses
held for sale or sold, including MSTI and TSG, had sales of approximately $412
million, $874 million and $964 million in 1996, 1995 and 1994, respectively, and
operating income (losses) before gains (charge) on disposition of businesses,
net of $(13) million, $5 million and $8 million in 1996, 1995 and 1994,
respectively.
 
     In late 1993, the Company adopted a plan to divest the business units in
its energy segment. Certain of the remaining business units were sold in 1994 at
prices greater than those used in estimating the loss on disposition in 1993,
resulting in a reversal in 1994 of approximately $18 million pre-tax ($11.7
million after-tax) of the charge established in 1993.
 
     Amounts included in the consolidated balance sheet for net assets of
businesses held for disposition consist of the following at December 31, 1996
and 1995:

     During 1994, the Company sold a portion of its common stock holdings in
TriMas, decreasing the Company's common equity ownership interest in TriMas to
41 percent, and resulting in a pre-tax gain of $17.9 million.
 
     In June, 1995, Titan sold newly issued common stock in a public offering
and issued common stock as a result of the conversion of convertible securities.
The Company recognized pre-tax income of approximately $5.1 million as a result
of the change in the Company's common equity ownership interest in Titan.
 
     In December, 1996, Titan called for redemption its 4 3/4% Convertible
Subordinated Notes which resulted in the issuance of approximately 4.5 million
common shares, reducing the Company's common equity

     The interest rates applicable to the revolving credit agreement are
principally at alternative floating rates provided for in the agreement
(approximately six percent at December 31, 1996). In early 1997, the Company
amended the revolving credit agreement; as a result, the new $575 million
revolving credit agreement is due 2002.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     The amended revolving credit agreement requires the maintenance of a
specified level of tangible shareholders' equity as defined, with limitations on
the ratios of senior debt to earnings and debt to equity (as defined). Under the
most restrictive of these provisions, approximately $70 million was available at
December 31, 1996 for the payment of cash dividends and the acquisition of
Company Capital Stock.
 
     The note held by Masco Corporation was part of the consideration paid by
the Company for the purchase of 17 million shares of MascoTech common stock and
warrants to purchase 10 million shares of MascoTech common stock from Masco
Corporation. Although the note payable to Masco Corporation is due September 30,
1997, it is classified as non-current at December 31, 1996 as the Company has
the intent and the ability to refinance this borrowing on a long-term basis.
 
     On March 15, 1995, the Company redeemed at maturity $233 million of its 10%
Senior Subordinated Notes utilizing its bank revolving credit agreement. During
1994, the Company recognized extraordinary income of $4.4 million pre-tax ($2.6
million after-tax) related to the early extinguishment of a portion of the
4 1/2% Convertible Subordinated Debentures.
 
     The maturities of debt during the next five years are as follows (taking
into account the amended credit agreement and assuming the short-term debt
referred to above is refinanced by the amended credit agreement) (in millions):
1997 - $3; 1998 - $3; 1999 - $3; 2000 - $3; and 2001 - $1.

Company or converted at the option of the holder, in both cases for Company
Common Stock.
 
     Each share of the DECS is convertible at the option of the holder anytime
prior to July 1, 1997 into .806 of a share of Company Common Stock, equivalent
to a conversion price of $24.81 per share of Company Common Stock. Dividends are
cumulative and each share of the DECS has 4/5 of a vote, voting together as one
class with holders of Company Common Stock.
 
     The Company, at its option, may redeem the DECS at a call price payable in
shares of Company Common Stock principally determined by a formula based on the
then current market price of Company Common Stock. Redemption by the Company, as
a practical matter, will generally not result in a call price that exceeds one
share of Company Common Stock or is less than .806 of a share of Company Common
Stock (resulting from the holder's conversion option).
 
     On October 31, 1996, the Company purchased from Masco Corporation 17
million shares of MascoTech common stock and warrants to purchase 10 million
shares of MascoTech common stock, for cash and notes approximating $266 million.
Payment of the note, which approximates $151 million and bears interest at 6 5/8
percent, is due September 30, 1997 and is payable in cash or at the Company's
option partially by the transfer of its holdings in its equity affiliate, Emco
Limited. As part of this transaction, Richard A. Manoogian, Chairman of both
Masco Corporation and MascoTech, also sold to MascoTech one million shares of
MascoTech common stock (at the then current market price) for approximately
$13.6 million, for cash and a $7.6 million note bearing interest at 6 5/8
percent, payable on September 30, 1997. In addition, as part of this
transaction, Masco Corporation's agreement to purchase from the Company, at the
Company's option, up to $200 million of subordinated debentures was extended
through 2002, and the corporate services agreement with Masco Corporation was
extended until September 30, 1998. Masco Corporation also agreed that MascoTech
will have the right of first refusal to purchase the approximate 7.8 million
shares of MascoTech common stock that Masco Corporation continues to hold,
should Masco Corporation decide to dispose of such shares.
 
     In addition, during each of 1996 and 1995, the Company repurchased and
retired approximately one million shares of its common stock in open-market
purchases, pursuant to a Board of Directors' authorized repurchase program. At
December 31, 1996, the Company may repurchase approximately four million
additional shares of Company Common Stock and Convertible Preferred Stock
pursuant to this repurchase authorization.
 
     Under a Stock Repurchase Agreement, Masco Corporation has the right to sell
to the Company, at approximate fair market value, shares of Company Common Stock
following the occurrence of certain events that would result in an increase in
Masco Corporation's ownership percentage in excess of 49 percent of the then
outstanding shares of Company Common Stock. Such events include repurchases of
Company Common Stock initiated by MascoTech or any of its subsidiaries, and
reacquisitions of Company Common Stock through forfeitures of shares previously
awarded by the Company pursuant to its employee stock incentive plans. In each
case, MascoTech has control over the amount of Company Common Stock it would
ultimately acquire, including shares subject to repurchase under the Stock
Repurchase Agreement. The aforementioned rights expire 30 days from the date
notice is given by MascoTech. To the extent these rights have been exercised at
any balance sheet date, the Company would reclassify from permanent capital an
amount representative of the repurchase obligation.
 
     On the basis of amounts paid (declared), cash dividends per common share
were $.18 ($.18) in 1996, $.14 ($.11) in 1995 and $.10 ($.11) in 1994.

STOCK OPTIONS AND AWARDS:
 
     The Company's Long-Term Stock Incentive Plan (the "Plan") provides for the
issuance of stock-based incentives in various forms. At December 31, 1996,
outstanding stock-based incentives are in the form of restricted long-term stock
awards and stock options.
 
     Pursuant to the Plan, the Company granted long-term stock awards, net, for
480,000, 461,000 and 213,000 shares of Company Common Stock during 1996, 1995
and 1994, respectively, to key employees of the Company and affiliated
companies. The weighted average grant date fair value per share of long-term
stock awards granted during 1996 and 1995 was $14 and $12, respectively.
Compensation expense for the vesting of long-term stock awards was approximately
$2.3 million, $4.8 million and $3.3 million in 1996, 1995 and 1994,
respectively. The unamortized costs of unvested stock awards, aggregating
approximately $26 million at December 31, 1996, are being amortized over the
ten-year vesting periods.
 
     Fixed stock options are granted to key employees of the Company and
affiliated companies and have a maximum term of 10 years. The exercise price of
each fixed option equals the market price of Company Common Stock on the date of
grant. These options either vest no later than 10 years after grant or in
installments beginning in the third year and extending through the eighth year
after grant.
 
     A summary of the status of the Company's stock options granted under the
Plan or prior plans for the three years ended December 31, 1996 is presented
below.

     At December 31, 1996, options have been granted and are outstanding with
exercise prices ranging from $4 1/2 to $26 per share, the fair market value at
the dates of grant.
 
     At December 31, 1996 and 1995, a combined total of 4,656,000 and 5,646,000
shares, respectively, of Company Common Stock were available for the granting of
options and incentive awards under the above plans.
 
     The Company has elected to continue to apply the provisions of Accounting
Principles Board Opinion No. 25 and, accordingly, no stock option compensation
expense is included in the determination of net income in the statement of
operations. The weighted average grant date fair value of options granted was
$6.20 in 1996. Had stock option compensation expense been determined pursuant to
the methodology of Statement of Financial Accounting Standards No. 123,
"Accounting for Stock-Based Compensation," the pro forma effects on the
Company's earnings and earnings per common share in 1996, 1995 and 1994 would
not have been material.

EMPLOYEE BENEFIT PLANS:
 
     Pension and Profit-Sharing Benefits. The Company sponsors defined-benefit
pension plans for most of its employees. In addition, substantially all salaried
employees participate in noncontributory profit-sharing plans, to which payments
are approved annually by the Directors. Aggregate charges to income under these
plans were $11.0 million in 1996, $13.0 million in 1995 and $9.8 million in
1994.

     Postretirement Benefits. The Company provides postretirement medical and
life insurance benefits for certain of its active and retired employees.
 
     The Company records its postretirement benefit plans in accordance with
Statement of Financial Accounting Standards No. 106 ("SFAS No. 106"),
"Employers' Accounting for Postretirement Benefits Other Than Pensions." This
statement requires the accrual method of accounting for postretirement health
care and life insurance based on actuarially determined costs to be recognized
over the period from the date of hire to the full eligibility date of employees
who are expected to qualify for such benefits. In conjunction with SFAS No. 106,
the Company recognizes the transition obligation on a prospective basis with the
net transition obligation amortized over 20 years. Net periodic postretirement
benefit cost includes the following components for the years ended December 31,

     The discount rate used in determining the accumulated postretirement
benefit obligation was 7.25 percent in both 1996 and 1995. The assumed health
care cost trend rate in 1996 was 12 percent, decreasing to an ultimate rate in
the year 2002 of seven percent. If the assumed medical cost trend rates were
increased by one percent, the accumulated postretirement benefit obligation
would increase by $1.6 million and the aggregate of the service and interest
cost components of net periodic postretirement benefit cost would increase by
$.2 million. Included in the Company's 1994 charge for the disposition of
certain businesses are curtailment costs for postretirement benefit obligations
relating to these businesses of approximately $3.7 million.

(A) Included within this segment are sales to one customer of $232 million, $397
    million and $361 million in 1996, 1995 and 1994, respectively; sales to
    another customer of $146 million, $182 million and $225 million in 1996,
    1995 and 1994, respectively; sales to a third customer of $122 million, $178
    million and $212 million in 1996, 1995 and 1994, respectively; and sales to
    a fourth customer of $155 million, $136 million and $111 million in 1996,
    1995 and 1994, respectively.
 
(B) Operating profit in 1996 includes a $32 million pre-tax loss principally
    from the sale of MascoTech Stamping Technologies, Inc. This charge impacted
    the Company's Transportation-Related Products and Services industry segment.
    Operating profit in 1995 includes $25 million in net gains resulting from
    sales of non-core businesses in the third quarter. These net gains were
    substantially offset by reductions in the estimated proceeds the Company
    expected to receive from businesses to be sold, aggregating $12 million, and
    by certain exit costs incurred in 1995 aggregating approximately $8 million.
    The net gains (charge) impact the Company's industry segments as follows:
    Transportation-Related Products and Services -- $21 million and Specialty
    Products -- $(2) million. The remaining $(14) million of the net gains
    (charge) was allocated to General Corporate Expense. Operating loss in 1994
    includes the impact of a pre-tax charge in the amount of $400 million for
    the disposition of businesses. The charge impacts the Company's industry
    segments as follows: Transportation-Related Products and Services -- $196
    million and Specialty Products -- $191 million. The remaining $13 million of
    the charge was allocated to General Corporate Expense.
 
(C) Assets employed at December 31, 1996, 1995 and 1994 include net assets
    related to the disposition of certain operations (see "Dispositions of
    Operations" note).
 
(D) Property additions include approximately $2 million and $14 million in 1996
    and 1995, respectively, of capital expenditures for those businesses held
    for disposition related to the plan adopted in late 1994.
 
(E) Depreciation and amortization expense include approximately $5 million in
    1995 of expense for those businesses held for disposition related to the
    plan adopted in late 1994.
 
(F) The Company's foreign operations are located principally in Western Europe.

FAIR VALUE OF FINANCIAL INSTRUMENTS:
 
     In accordance with Statement of Financial Accounting Standards No. 107,
"Disclosures about Fair Value of Financial Instruments," the following methods
were used to estimate the fair value of each class of financial instruments:
 
MARKETABLE SECURITIES, NOTES RECEIVABLE AND OTHER ASSETS
 
     Fair values of financial instruments included in marketable securities,
notes receivable and other assets were estimated using various methods including
quoted market prices and discounted future cash flows based on the incremental
borrowing rates for similar types of investments. In addition, for variable-rate
notes receivable that fluctuate with the prime rate, the carrying amounts
approximate fair value.
 
LONG-TERM DEBT
 
     The carrying amount of bank debt and certain other long-term debt
instruments approximate fair value as the floating rates inherent in this debt
reflect changes in overall market interest rates. The fair values of the
Company's subordinated debt instruments are based on quoted market prices. The
fair values of certain other debt instruments are estimated by discounting
future cash flows based on the Company's incremental borrowing rate for similar
types of debt instruments.
 
     The carrying amounts and fair values of the Company's financial instruments
at December 31, 1996 and 1995 are as follows:

     Since dilution occurs in the first quarter 1996, earnings per common share
is presented on a fully diluted basis. However, earnings per common share on
income before accounting change item is anti-dilutive.
 
     Results for the second quarter 1996 include an after-tax loss of
approximately $26 million related to the sale of MascoTech Stamping
Technologies, Inc.
 
     Net income for the first quarter of 1996 includes an after-tax gain of
approximately $12 million as a result of the adoption of Statement of Financial
Accounting Standards No. 121, "Accounting for the Impairment of Long-Lived
Assets and for Long-Lived Assets to Be Disposed Of," effective January 1, 1996
which was recorded as a cumulative effect of an accounting change.
 
     The 1996 income (loss) per common share amounts for the quarters do not
total to the full year amounts due to the purchase and retirement of shares
throughout the year.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONCLUDED)
 
     Results for the third quarter of 1995 include net gains aggregating
approximately $25 million from the sale of certain businesses held for
disposition. These net gains were offset by reductions in the estimated net
proceeds the Company expected to receive from businesses to be sold, aggregating
$12 million and by certain exit costs incurred in 1995 aggregating approximately
$8 million.
 
     Results for the second quarter of 1995 include pre-tax income of
approximately $5 million as a result of gains associated with the sale of common
stock through a public offering by an equity affiliate.
 
     The following supplemental unaudited financial data combine the Company
with TriMas and have been presented for analytical purposes. The Company had a
common equity ownership interest in TriMas of approximately 41 percent at
December 31, 1996 and December 31, 1995. The interests of the other common
shareholders are reflected below as "Equity of other shareholders of TriMas."
All significant intercompany transactions have been eliminated.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Board of Directors
and Shareholders of TriMas Corporation:
 
     We have audited the consolidated financial statements and the financial
statement schedule of TriMas Corporation and subsidiaries listed in Item
14(a)(2)(ii)(A) and (B) of this Form 10-K. These financial statements and
financial statement schedule are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements and
financial statement schedule based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of TriMas
Corporation and subsidiaries as of December 31, 1996 and 1995, and the
consolidated results of their operations and their cash flows for each of the
three years in the period ended December 31, 1996 in conformity with generally
accepted accounting principles. In addition, in our opinion, the financial
statement schedule referred to above, when considered in relation to the basic
financial statements taken as a whole, presents fairly, in all material
respects, the information required to be included therein.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE 1. ACCOUNTING POLICIES
 
PRINCIPLES OF CONSOLIDATION
 
     The consolidated financial statements include the accounts of TriMas
Corporation and its wholly owned subsidiaries (the "Company"). All significant

accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
AFFILIATES
 
     As of December 31, 1996 MascoTech, Inc.'s common stock ownership in the
Company approximated 41.5 percent, and Masco Corporation's common stock
ownership approximated 4.3 percent. The Company has a corporate services
agreement with Masco Corporation. Under the terms of the agreement, the Company
pays a fee to Masco Corporation for various corporate support staff,
administrative services, and research and development services. Such fee equals
 .8 percent of the Company's net sales, subject to certain adjustments, and
totaled $3.3 million, $3.1 million and $3.0 million in 1996, 1995 and 1994.
 
CASH AND CASH EQUIVALENTS
 
     The Company considers all highly liquid debt instruments purchased with a
maturity of three months or less to be cash equivalents. At December 31, 1996
the Company had $84.8 million invested in prime commercial paper of several
United States issuers having the highest rating given by one of the two
principal rating agencies.
 
RECEIVABLES
 
     Receivables are presented net of an allowance for doubtful accounts of $1.9
million and $1.5 million at December 31, 1996 and 1995.
 
INVENTORIES
 
     Inventories are stated at the lower of cost or net realizable value, with
cost determined principally by use of the first-in, first-out method.
 
PROPERTY AND EQUIPMENT
 
     Property and equipment additions, including significant betterments, are
recorded at cost. Upon retirement or disposal of property and equipment, the
cost and accumulated depreciation are removed from the accounts and any gain or
loss is included in income. Maintenance and repair costs are charged to expense
as incurred.
 
DEPRECIATION AND AMORTIZATION
 
     Depreciation is computed principally using the straight-line method over
the estimated useful lives of the assets. Annual depreciation rates are as
follows: buildings and land improvements, 2 1/2 to 5 percent, and machinery and
equipment, 6 2/3 to 33 1/3 percent. The excess of cost over net assets of
acquired companies is being amortized using the straight-line method over the
periods estimated to be benefited, not exceeding

NOTE 1. ACCOUNTING POLICIES (CONTINUED)

40 years. At December 31, 1996 and 1995, accumulated amortization of the excess
of cost over net assets of acquired companies and other intangible assets was
$36.6 million and $31.3 million. Amortization expense was $5.3 million, $5.0
million and $5.3 million in 1996, 1995 and 1994.
 
     As of each balance sheet date management assesses whether there has been an
impairment in the value of excess of cost over net assets of acquired companies
by comparing anticipated undiscounted future cash flows from the related
operating activities with the carrying value. The factors considered by
management in performing this assessment include current operating results,
trends and prospects, as well as the effects of obsolescence, demand,
competition and other economic factors. Based on this assessment there was no
impairment at December 31, 1996.
 
FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The carrying values of financial instruments classified in the balance
sheet as current assets and current liabilities approximate fair values. The
fair value of notes receivable, a portion of which is included in both
receivables and other assets, based on discounted cash flows using current
interest rates, approximates the carrying value of $9.6 million at December 31,
1996.
 
     The carrying amount of borrowings from banks approximates fair value as the
floating rates applicable to this debt generally reflect changes in overall
market interest rates. The fair value of the Company's Convertible Subordinated
Debentures, based on quoted market prices, was $124.8 million at December 31,
1996 and $112.7 million at December 31, 1995, as compared to the carrying value
on such dates of $115.0 million.
 
FOREIGN CURRENCY TRANSLATION
 
     Net assets of the Company's operations outside of the United States are
translated into U.S. dollars using current exchange rates with the effects of
translation adjustments deferred and included as a separate component of
shareholders' equity. Revenues and expenses are translated at the average rates
of exchange during the period.
 
EARNINGS PER COMMON SHARE
 
     Primary earnings per common share in 1996, 1995 and 1994 were calculated on
the basis of 37.0 million weighted average common and common equivalent shares
outstanding. Fully diluted earnings per common share in 1996, 1995 and 1994 were
calculated on the basis of 42.1 million weighted average common and common
equivalent shares outstanding.

NOTE 2. ACQUISITIONS
 
     In June 1996 the Company acquired Queensland Towbars Pty. Ltd.
("Queensland"), in July it acquired The Englass Group Limited ("Englass"), and
in the fourth quarter it acquired Heinrich Stolz GmbH ("Stolz") and Beaumont
Bolt & Gasket Co. ("Beaumont"), all for an aggregate $54.2 million of cash and
assumed liabilities. The acquisitions were accounted for as purchases. The
aggregate excess of cost over net assets acquired of $28.8 million is being
amortized on a straight-line basis over 40 years. The results of operations of
the acquired businesses have been included in the consolidated financial
statements from the respective acquisition dates. Additional purchase price
amounts, contingent upon the achievement of specified levels of future
profitability by certain of the businesses, may be payable in 1997. These
payments, if required, will be recorded as additional excess of cost over net
assets of acquired companies.
 
     Englass is a United Kingdom-based supplier of specialty dispensing and
packaging products with applications in toiletry, pharmaceutical, veterinary,
food and consumer household markets. Stolz, based in Neunkirchen, Germany,
manufactures a wide variety of closures for industrial packaging markets.
Queensland is Australia's second largest manufacturer of vehicle hitches and
towing products. Beaumont, based in Texas, manufactures and distributes
specialty metallic and nonmetallic gaskets, and complementary bolts and
fasteners used in the refinery, chemical and petrochemical industries.
 
     On a pro forma, unaudited basis, as if the 1996 acquisitions had all
occurred as of January 1, 1995, net sales, net income, primary earnings per
common share and fully diluted earnings per common share for 1996 would have
been $631.5 million, $63.1 million, $1.71 and $1.59, and net sales, net income,
primary earnings per common share and fully diluted earnings per common share
for 1995 would have been $592.6 million, $57.6 million, $1.56 and $1.46.

     At December 31, 1996 borrowings from banks are owing under the Company's
domestic $350.0 million revolving credit facility ($33.0 million), its L20.0
million revolving credit facility in England ($19.3 million), its DM 30.0
million revolving credit facility in Germany ($9.0 million) and other borrowing
arrangements in Germany ($6.7 million). At December 31, 1995 borrowings from
banks were owing under the domestic facility. The domestic facility permits the
Company to borrow under several different interest rate options, while the
foreign facilities base interest rates on the London Interbank Offered Rate
(LIBOR). At December 31, 1996 the blended interest rate on bank borrowings
equaled 5.9 percent. The facilities contain certain restrictive covenants, the
most restrictive of which, at December 31, 1996, required $270.1 million of
shareholders' equity. The Company had available credit of $341.8 million under
its revolving credit facilities at December 31, 1996.
 
     During February 1997 TriMas called for redemption, on March 21, 1997, its
outstanding issue of $115.0 million of 5% Convertible Subordinated Debentures
Due 2003. The Debentures are convertible at the option of the holders through
March 20, 1997 into shares of Company common stock at a conversion price of
$22 5/8 per share. The Company currently plans to use long-term borrowings under
its domestic revolving credit facility to redeem the Debentures. The redemption
price for the Debentures will be 103.33 percent of the principal amount. Any
premium and unamortized debt issuance costs associated with the Debentures
redeemed will be recorded as an extraordinary charge, on an after tax basis, in
the first quarter of 1997.

     Under a Stock Repurchase Agreement which expires in December 1998, Masco
Corporation and MascoTech, Inc. have the right to sell to the Company, at
approximate fair market value, shares of Company common stock following the
occurrence of certain events that would result in an increase in their
respective ownership percentage of the then outstanding shares of Company common
stock. Such events include repurchases of Company common stock initiated by
TriMas or any of its subsidiaries, and reacquisitions of Company common stock
through forfeitures of shares previously awarded by the Company pursuant to its
employee stock incentive plans. In each case, TriMas has control over the amount
of Company common stock it would ultimately acquire, including shares subject to
repurchase under the Stock Repurchase Agreement. The aforementioned rights
expire 30 days from the date notice of an event is given by TriMas and neither
Masco Corporation nor MascoTech, Inc. have ever exercised their right to sell
Company common stock to the Company. To the extent these rights have been
exercised at any balance sheet date, the Company would reclassify from permanent
capital an amount representative of the repurchase obligation.

NOTE 9. STOCK OPTIONS AND AWARDS
 
     The Company's stock incentive plans include the TriMas Corporation 1995
Long Term Stock Incentive Plan, the 1988 Restricted Stock Incentive Plan and the
1988 Stock Option Plan. Company common stock available for grant under these
plans includes the 2,000,000 shares initially established under the 1995 plan,
plus additional shares resulting from certain reacquisitions of shares by the
Company.
 
     The Company granted long-term incentive awards of Company common stock,
net, for 159,071 shares in 1996, 290,588 shares in 1995 and 88,118 shares in
1994, to key employees of the Company. The weighted average fair value per
share, on date of grant, of long-term incentive awards granted in 1996 and 1995
was $19.66 and $23.21. Compensation expense recorded in 1996, 1995 and 1994
related to long-term incentive awards was $2.2 million, $1.6 million and $1.2
million. The unamortized costs of incentive awards, aggregating $14.0 million at
December 31, 1996, are being amortized over the ten year vesting periods.
 
     Fixed stock options are granted to key employees of the Company and have a
maximum term of ten years. The exercise price of each fixed option equals the
market price of the Company's common stock on the date of grant. The options
generally vest in installments beginning in the second year and extending
through the eighth year after grant. For the three years ended December 31, 1996
stock option information is as follows:

     The Company applies Accounting Principles Board Opinion No. 25, Accounting
for Stock Issued to Employees, in accounting for stock based compensation.
Accordingly, no compensation expense has been charged against income for fixed
stock option grants. Had compensation expense been determined based on the fair
value at the 1996 and 1995 grant dates, consistent with the methodology of
Statement of Financial Accounting Standards No. 123, Accounting for Stock-Based
Compensation, the pro forma effects on the Company's net income and earnings per
share would not have been material.
 
     At December 31, 1996 and 1995, a combined total of 2,011,642 and 2,055,803
shares of Company common stock were available for the granting of options and
incentive awards under the aforementioned plans.

     Contributions to profit-sharing and other defined contribution plans are
generally determined as a percentage of the covered employee's annual salary.
 
     Defined benefit plans provide retirement benefits for salaried employees
based primarily on years of service and average earnings for the five highest
consecutive years of compensation. Defined benefit plans covering hourly
employees generally provide benefits of stated amounts for each year of service.
These plans are funded based on an actuarial evaluation and review of the
assets, liabilities and requirements of each plan. Plan assets are held by a
trustee and invested principally in cash equivalents and marketable equity and
fixed income instruments.
 
     Net periodic pension cost of defined benefit plans includes the following
components:

     The Company provides postretirement health care and life insurance benefits
for certain eligible retired employees under unfunded plans. Some of the plans
have cost-sharing provisions. Net periodic postretirement benefit costs during
1996, 1995 and 1994 were $1.0 million, $.8 million and $.8 million.
 
     The aggregate accumulated postretirement benefit obligation of these
unfunded plans was $7.1 million at both December 31, 1996 and 1995. The discount
rates used in determining the accumulated postretirement benefit obligations and
the net periodic postretirement benefit costs were 7.5 percent, 7.3 percent and
8.5 percent in 1996, 1995 and 1994. The assumed health care cost trend rate in
1996 was 12.0 percent, decreasing to an ultimate rate in the years subsequent to
2001 of seven percent. A one percent increase in the assumed health care cost
trend rates would have increased the net periodic postretirement benefit cost by
$.1 million during 1996 and would have increased the accumulated postretirement
benefit obligation at December 31, 1996 by $.9 million. The Company is
amortizing the unrecognized transition accumulated postretirement benefit
obligation and subsequent plan net gains and losses in accordance with Statement
of Financial Accounting Standards No. 106. The accrued postretirement benefit
obligation was $3.5 million and $3.1 million at December 31, 1996 and 1995.

     Earnings per common share in the fourth quarter of 1996 and 1995 were
improved by $.06 and $.07, net, resulting from year end adjustments to estimates
recorded earlier in each year. Amounts adjusted include rebates from raw
material suppliers, required year end insurance reserves and incentive
compensation accruals whose final determinations require actual results for the
year. Quarterly earnings per common share amounts for both 1996 and 1995 do not
total to the full year amounts due to rounding.

Existing Agent (as hereinafter defined) have entered into the Existing Credit

funds for its general corporate purposes.

     C.       The Banks are willing to provide such a replacement revolving
credit facility on the terms and conditions set forth in this Agreement.

     NOW, THEREFORE, in consideration of the premises and of the mutual promises
contained herein, the parties hereto agree as follows:


                                   ARTICLE I.

                                  DEFINITIONS


     1.1      Certain Definitions.  As used in this Agreement, and in any
certificate, report, other agreement or other document made or delivered

     "Adjusted Net Worth" means, as of any date, the sum of (a) Net Worth, plus

Office, Eurodollar Lending Office or any other office of such Bank or of any
Affiliate of such Bank selected and notified to the Company and the Agent as the

attached hereto by reading down the column of Senior Leverage Ratio ranges to
the row for the range into which the Senior Leverage Ratio as of the relevant
Determination Date falls, and then reading across that row to the Interest
Coverage Ratio column for the range into which the Interest Coverage Ratio for
the relevant Determination Period falls.  By way of example, if the Senior

taking effect pursuant to this definition, but any change in the Applicable
Margin while any Letter of Credit is outstanding shall not be effective with
respect to such Letter of Credit for any quarterly period for which the fee for
such Letter of Credit has already been paid under Section 3.3(c).  For purposes
of determining the Applicable Margin,

all Stock Redemptions (other than any issuance or redemption, purchase,
retirement or other acquisition in connection with the Company's employee stock
award programs), or if the payments resulting from all Stock Redemptions, net of
the proceeds resulting from all Stock Issuances, within 45 days after a
Determination Date, exceed $10,000,000, the Senior Leverage Ratio shall be
calculated on a pro forma basis to reflect the effect of all Stock Issuances and
Stock Redemptions (other than any issuance or redemption, purchase retirement or
other acquisition in

of the proceeds resulting from all Stock Issuances, from the beginning of a
Determination Period through and including the 45th day after the end of such
Determination Period exceeds $10,000,000, the Interest Coverage Ratio for such
Determination Period shall be calculated on a pro forma basis as if each such

redemption, purchase, retirement or other acquisition in connection with the
Company's employee stock award programs) and the related application of proceeds
or funding or payment thereof had occurred on the first day of such
Determination Period.

Notwithstanding anything in this definition of "Applicable Margin" to the
contrary, if the Company has a Senior Debt Rating at any time, including at any
time prior to the end of an Application Period, the Applicable Margin shall
change on the date such Senior Debt Rating is effective such that the Applicable
Margin is (x) 0.25% for Eurodollar Rate Syndicated Loans and, subject to clause
(d) above, Letters of Credit, (y) 0.375% for CD Rate Loans and (z) 0.10% for

          Day,

               (B)      the aggregate amount of such Borrowing,

          (a)      Subject to the terms and conditions set forth in this

Credit Obligations Amount shall not at any time exceed the lesser of (i)

Credit shall have a stated expiry date earlier than 30 days after the date of
its issuance, and no Letter of Credit shall have a stated expiry date or, if by
its terms it is periodically renewable, be subject to being terminated by the
Agent (unless renewal is permitted by the Agent in its sole discretion, in which
case the Agent will not permit renewal to a date beyond that determined in
accordance with the following portion of this sentence), later than the earlier

shall be in a minimum amount of $1,000,000.  Subject to the terms and conditions
set forth in this Agreement, the Agent shall, on the date any Letter of Credit
is requested to be issued, issue the related Letter of Credit for the pro rata
risk of the Banks.  Notwithstanding anything herein to the contrary, the Agent
may decline to issue any Letter of Credit if the beneficiary or the conditions
of drawing are reasonably unacceptable to the Agent, or if the purpose of
issuance is illegal or is in contravention of any law, rule, regulation or
public policy or any judgment, decree, writ, injunction, order or award of any
arbitrator, court or governmental authority.

          (b)      The Company shall give the Agent written notice in
substantially the form attached hereto as Exhibit D (a "Request for Letter of
Credit Issuance") not later than 10:00 a.m. (Detroit time) on the fifth Business
Day before each requested Letter of Credit Issuance or such later time as is
acceptable to the Agent.

          (c)      The Company agrees (i) to pay to the Agent for the account of
the Banks a fee computed at the per annum rate equal to the Applicable Margin of
the maximum amount available to be drawn from time to time under the related
Letter of Credit for the period from and including the date of such Letter of
Credit Issuance to but excluding the stated expiry date of such Letter of
Credit, and (ii) to pay an additional fee to the Agent for its own account
computed at the rate of one-eighth of one percent (1/8 of 1%) per annum of such
maximum amount for such period, such fees with respect to any Letter of Credit
to be paid quarterly in advance commencing with the date of its issuance, based
upon the Applicable Margin in effect at the beginning of each such quarter.
Such fees are nonrefundable and the Company shall not be entitled to any rebate
of any  portion thereof if such Letter of Credit does not remain outstanding
through such quarter or for any other reason.  The Company further agrees to pay
to the Agent, on demand, such other customary administrative fees, charges and
expenses of the Agent in respect of the issuance, negotiation, 



                      MASCOTECH, INC. CREDIT AGREEMENT


                                    -19-

acceptance, amendment, transfer and payment of such Letter of Credit or
otherwise payable pursuant to the application and related documentation under
which such Letter of Credit is issued.

          (d)      Nothing in this Agreement shall be construed to require or
authorize any Bank to issue any Letter of Credit, it being recognized that the
Agent has the sole obligation under this Agreement to issue Letters of Credit
for the risk of the Banks.  Upon each Letter of Credit Issuance, each Bank shall
automatically acquire a pro rata risk participation interest in the related
Letter of Credit based on its respective Commitment Percentage.  If the Agent
shall honor a draft or other demand for payment presented or made under any
Letter of Credit, the Agent shall provide notice thereof to each Bank on the
date such draft or demand is honored unless the Company shall have satisfied its
reimbursement obligation under subsection (e) of this Section 3.3 by payment to
the Agent on such date.  Each Bank, on such date, shall make an amount equal to
its Commitment Percentage of the amount paid by the Agent available in
immediately available funds at the principal office of the Agent for the account
of the Agent.  If and to the extent such Bank shall not have made such amount
available to the Agent, such Bank and the Company severally agree to pay to the
Agent forthwith on demand such amount, together with interest thereon for each
day from the date such amount was paid by the Agent until such amount is so made
available to the Agent at (i) in the case of such Bank, the Federal Funds Rate
and (ii) in the case of the Company, the per annum rate equal to the interest
rate applicable during such period to the related Borrowing deemed (or that
could have been deemed) disbursed under subsection (e) of this Section 3.3 in
respect of the reimbursement obligation of the Company.  If such Bank shall pay
such amount to the Agent together with such interest, if any, accrued, such
amount so paid shall constitute a Syndicated Loan by such Bank as part of the
Borrowing disbursed in respect of the reimbursement obligation of the Company
under subsection (e) of this Section 3.3 for purposes of this Agreement.  The
failure of any Bank to make an amount equal to its Commitment Percentage of any
such amount paid by the Agent available to the Agent shall not relieve any other
Bank of its obligation to make available an amount equal to such other Bank's
Commitment Percentage of such amount, but no Bank shall be responsible for
failure of any other Bank to make its share available to the Agent.

          (e)(i) Whether a Letter of Credit was issued for the account of the
Company or any Consolidated Subsidiary of the Company, and without limiting the
reimbursement obligation of such Consolidated Subsidiary, the Company agrees to
pay to the Agent, not later than 3:00 p.m.  (Detroit time) on the date on which
the Agent shall honor a draft or other demand for payment presented or made
under such Letter of Credit, an amount equal to the amount paid by the Agent in
respect of such draft or other demand under such Letter of Credit and all
expenses paid or incurred by the Agent relative thereto (the "Reimbursement
Amount").  The Agent shall, on the date of each demand for payment under any
Letter of Credit, give the Company notice thereof and of the amount of the
Company's reimbursement obligation and liability for expenses relative thereto;
provided that the failure of the Agent to give such notice shall not affect the
reimbursement and other obligations of the Company under this Section 3.3.
Unless the Company shall have made such payment to the Agent on such day, upon
each such payment by the Agent, the Company shall be deemed to have elected to
satisfy its reimbursement obligation by a Floating Rate Borrowing in an amount
equal to the amount so paid by the Agent in respect of such draft or other
demand under such Letter of Credit, and the Agent shall be deemed to have
disbursed to the Company, for the account of the Banks, the Floating Rate Loans
comprising such Floating Rate Borrowing, and each Bank shall make its share of
each such Floating Rate Borrowing available to the Agent in accordance with
Section 3.5(b).  Such Floating Rate Loans shall be deemed disbursed
notwithstanding any failure to satisfy any conditions for disbursement of any
Loan set forth in Article VIII and, to the extent of the Floating Rate Loans so
disbursed, the reimbursement obligation of the Company under this subsection
(e)(i) shall be deemed satisfied.

               (ii)    If, for any reason (including without limitation as a
result of the occurrence of an Event of Default with respect to the Company
pursuant to Section 9.1(f) or (g)), Floating Rate Loans may not be made by the
Banks as described in Section 3.3(e)(i), then (A) the Company agrees that each

3.3(e)(i) shall bear interest, payable on demand by the Agent, at the interest
rate then applicable to Floating Rate Loans, and (B) effective on the date each
such Floating Rate Loan would otherwise have been made, each Bank severally
agrees that it shall unconditionally and irrevocably, without regard to the
occurrence of any Default, to the extent of such Bank's Commitment Percentage,
purchase a participating interest in each Reimbursement Amount. Each Bank will
immediately transfer to the Agent, in same day funds, the amount of its
participation.  Each Bank shall share on a pro rata basis (calculated by
reference to its Commitment Percentage) in any interest which accrues thereon
and in all repayments thereof.  If and to the extent that any Bank shall not
have so made the amount of such participating interest available to the Agent,
such Bank agrees to pay to the Agent forthwith on demand such amount together
with interest thereon, for each day from the date of demand by the Agent until
the date such amount is paid to the Agent, at the Federal Funds Rate.

          (f)      The reimbursement obligation of the Company under this
Section 3.3 with respect to each Letter of Credit shall be absolute,
unconditional and irrevocable and shall remain in full force and effect until
all such obligations of the Company to the Banks and the Agent with respect to
such Letter of Credit shall have been satisfied, and such obligations of the
Company shall not be affected, modified or impaired upon the happening of any
event, including without limitation, any of the following, whether or not with
notice to, or the consent of, the Company:

               (i)      Any lack of validity or enforceability of any Letter of
Credit or any documentation relating to any Letter of Credit or to any
transaction related in any way to such Letter of Credit (the "Letter of Credit
Documents");

               (ii)      Any amendment, modification, waiver, consent, or any
substitution, exchange or release of or failure to perfect any interest in
collateral or security, with respect to any of the Letter of Credit Documents;

               (iii)      The existence of any claim, setoff, defense or other
right which the Company may have at any time against any beneficiary or any
transferee of any Letter of Credit (or any persons or entities for whom any such
beneficiary or any such transferee may be acting), the Agent or any Bank or any
other Person, whether in connection with any of the Letter of Credit Documents,
the transactions contemplated herein or therein or any unrelated transactions;

               (iv)      Any draft or other statement or document presented
under any Letter of Credit proving to be forged, fraudulent, invalid or
insufficient in any respect or any statement therein being untrue or inaccurate
in any respect;

               (v)      Payment by the Agent to the beneficiary under any Letter
of Credit against presentation of documents which do not comply with the terms
of the Letter of Credit, including failure of any documents to bear any
reference or adequate reference to such Letter of Credit;

               (vi)      Any failure, omission, delay or lack on the part of the
Agent or any Bank or any party to any of the Letter of Credit Documents to
enforce, assert or exercise any right, power or remedy conferred upon the Agent,
any Bank or any such party; or


               (vii)      Any other event or circumstance that would, in the
absence of this clause, result in the release or discharge by operation of law
or otherwise of the Company from the performance or observance of any
obligation, covenant or agreement contained in this Section 3.3.

No setoff, counterclaim, reduction or diminution of any obligation or any
defense of any kind or nature which the Company has or may have against the
beneficiary of any Letter of Credit shall be available hereunder to

aggregate amount of the Commitments over (B) the sum of (x) the aggregate
outstanding principal amount of Syndicated Loans plus (y) the Letter of Credit
Obligations Amount, or (ii) fifty percent (50%) of the aggregate amount of the
Commitments (as the same may be reduced in accordance with the terms of this
Agreement during any applicable Bid-Option Interest Period); and provided,
further, that the Dollar Equivalent of the aggregate outstanding principal
amount of Foreign Currency Bid-Option Loans shall not exceed $50,000,000.

          (b)      Bid-Option Quote Requests.  When the Company wishes to
request offers to make Bid-Option Loans under this Section, it shall transmit to
the Agent by telex or telecopy a request substantially in the form attached

                  Foreign Currency Bid-Option, the desired Foreign Currency;

          (C)     the aggregate amount of such Borrowing, which shall be (A)
                  $25,000,000 or a larger multiple of $5,000,000, in the case of
                  a Dollar Bid-Option Borrowing, or (B) not less than the Dollar
                  Equivalent of $5,000,000, in the case of a Foreign Currency
                  Bid-Option Borrowing; and

          (D)     the duration of the Interest Period applicable thereto,
                  subject to the provisions of the definition of the applicable
                  Interest Period.

          (C)     the principal amount of the Bid-Option Loan for which each
                  such offer is being made, the Dollar Equivalent of which (1)
                  may, together with the Dollar Equivalent of the aggregate
                  outstanding principal amount of all other Loans made by the
                  quoting Bank, exceed the amount of the Commitment of the

                  related Invitation for Bid-Option Quotes;

          (D)     in the case of a Bid-Option Auction for Absolute Rate Dollar
                  Bid-Option Loans or Foreign Currency Bid-Option Loans, the
                  rate of interest per annum (rounded up to the nearest
                  1/10,000th of 1%) (the "Bid-Option Absolute Rate") offered for
                  each such Bid-Option Loan;

          (E)     in the case of a Bid-Option Auction for Eurodollar Rate Dollar
                  Bid-Option Loans, the applicable margin, which may be positive

                  Rate or Bid-Option Eurodollar Rate Margin, as the case may be,
                  is offered; and

          (G)     the identity of the quoting Bank.

                  (iii)      Any Bid-Option Quote shall be disregarded if it:

          (A)     is not substantially in the form of Exhibit G hereto or does
                  not specify all of the information required by subsection
                  (d)(ii) above;

          (B)     contains qualifying, conditional or similar language;

          (C)     proposes terms other than or in addition to those set forth in
                  the applicable Invitation for Bid-Option Quotes; or

          (D)     arrives after the time set forth in subsection (d)(i);

provided that a Bid-Option Quote shall not be disregarded pursuant to clause
(B) or (C) above solely because it indicates that an allocation that might
otherwise be made to it pursuant to Section 3.4(g) would be unacceptable.

          (e)      Notice to Company.  The Agent shall promptly notify the
Company of the terms (i) of any Bid-Option Quote submitted by a Bank that is in
accordance with subsection (d) of this Section and (ii) of any Bid-Option Quote
that amends, modifies or is otherwise inconsistent with a previous Bid-Option
Quote submitted by such Bank with respect to the same Bid-Option Quote Request.
Any such subsequent Bid-Option Quote shall be disregarded by the Agent unless
such subsequent Bid-Option Quote is submitted solely to correct a manifest error
in such former Bid-Option Quote.  The Agent'sEnotice to the Company shall
specify (i) the Dollar Equivalent of the aggregate principal amount of
Bid-Option Loans for which offers have been received for each Interest Period
specified in the related Bid-Option Quote Request and (ii) the respective Dollar
Equivalent of the principal amounts and respective Bid-Option Absolute Rates or
Bid-Option Eurodollar Rate Margins, as the case may be, so offered.

          (f)      Acceptance and Notice by Company.  Not later than 10:00 a.m.
(Detroit time) on (i) the proposed date of the Borrowing, in the case of a
Bid-Option Auction for Absolute Rate Dollar Bid-Option Loans, (ii) the third
Business Day prior to the proposed date of the Borrowing, in the case of a
Bid-Option Auction for Eurodollar Rate Dollar Bid-Option Loans, or (iii) the
second Business Day prior to the proposed date of the Borrowing, in the case of
a Bid-Option Auction for Foreign Currency Bid-Option Loans, the Company shall
notify the Agent of its acceptance or non-acceptance of the offers so notified
to it pursuant to subsection (e) of this Section 3.3.  In the case of
acceptance, such notice (a "Notice of Bid-Option Borrowing") shall specify the
aggregate principal amount of accepted offers for the applicable Interest
Period(s).  The Company may accept any Bid-Option Quote in whole or in part;
provided that:

          (A)     the Dollar Equivalent of the aggregate principal amount of
                  each Bid-Option Borrowing may not exceed the applicable amount
                  set forth in the related Bid-Option Quote Request;

          (B)     the Dollar Equivalent of the aggregate principal amount of
                  each Bid-Option Borrowing must be (1) in the case of Dollar
                  Bid-Option Borrowings, $25,000,000 or a larger multiple of
                  $5,000,000, unless the aggregate amount of the related
                  Bid-Option Loans for which Bid-Option Quotes were
                  received is less than $25,000,000, in which case the aggregate
                  principal amount of the Dollar Bid-Option Borrowing may be any
                  amount less than $25,000,000, and (2) in the case of Foreign
                  Currency Bid-Option Loans, not less than $5,000,000 (or, if
                  less, the aggregate amount of the related Bid-Option Loans for
                  which Bid-Option Quotes were received);

          (C)     acceptance of offers may only be made on the basis of
                  ascending Bid-Option Absolute Rates or Bid-Option Eurodollar
                  Rate Margins, as the case may be; and

          (D)     the Company may not accept any offer that is described in
                  clause (iii) of subsection (d) of this Section or that
                  otherwise fails to comply with the requirements of this
                  Agreement.

          (g)      Allocation by Agent.  If offers are made by two or more Banks
with the same Bid-Option Absolute Rates or Bid-Option Eurodollar Rate Margins,
as the case may be, for a greater aggregate principal amount than the amount in
respect of which offers are accepted for the related Interest Period, the
principal amount of Bid-Option Loans in respect of which such offers are
accepted shall be allocated by the Agent among such Banks as nearly as possible
(in such multiples, not greater than the Dollar Equivalent of $500,000, as the
Agent may deem appropriate) in proportion to the aggregate principal amount of
such offers (excluding any Bank that has indicated in its offer that an
allocation which otherwise would be made to it is unacceptable). Determinations
by the Agent of the amounts of Bid-Option Loans shall be conclusive in the
absence of manifest error.

     3.5     Notice to Banks; Funding of Loans.   (a)  Upon receipt of a Notice
of Borrowing or Request for Letter of Credit Issuance, the Agent shall promptly
notify each Bank of the contents thereof and of such Bank's share, if any, of
such Borrowing or the related Letter of Credit risk, as the case may be.  A
Notice of Borrowing or Request for Letter of Credit Issuance shall be
irrevocable by the Company once the Agent begins notifying any Bank of the
contents thereof.

          (b)      Each Bank, not later than 1:00 p.m. (Detroit time) on the
date any Borrowing is requested to be made, other than a Foreign Currency
Bid-Option Borrowing, shall (except as provided in subsection (d) of this
Section 3.5) make its share, if any, of such Borrowing available to the Agent in
immediately available funds, at the Agent'sEaddress specified in or pursuant to
Section 11.2, for disbursement to the Company.  Unless the Agent determines that
any applicable condition specified in Article VIII has not been satisfied, the
Agent will make funds actually so received from the Banks available to the
Company at the Agent's aforesaid address.  Unless the Agent shall have received
notice from any Bank prior to the date such Borrowing is requested to be made
that such Bank will not make available to the Agent such Bank's share of such
Borrowing, the Agent may assume that such Bank has made such share available to
the Agent on the date such Borrowing is requested to be made in accordance with
this Section 3.5.  If and to the extent such Bank shall not have so made such
share available to the Agent, the Agent may (but shall not be
obligated to) make such amount available to the Company, and such Bank and the
Company severally agree to pay to the Agent forthwith on demand such amount,
together with interest thereon for each day from the date such amount is made
available to the Company by the Agent until the date such amount is repaid to
the Agent at (i) in the case of such Bank, the Federal Funds Rate and (ii) in
the case of the Company, a rate per annum equal to the interest rate applicable
to such Borrowing during such period.  If such Bank shall pay such amount to
the Agent together with interest, such amount so paid shall constitute a Loan
by such Bank as a part of the related Borrowing for purposes of this Agreement.
The failure of any Bank to make its share of any Borrowing available to the
Agent shall not relieve any other Bank of its obligation to make available to
the Agent its share, if any, of such Borrowing on the date such Borrowing is
requested to be made, but no Bank shall be responsible for failure of any other
Bank to make such share available to the Agent on the date of such Borrowing.

          (c)      Each Bank, not later than 11:00 a.m. (Detroit time) on the
date any Foreign Currency Bid-Option Borrowing is requested to be made shall
(except as provided in subsection (d) of this Section 3.5) make its share, if
any, of such Borrowing available to the Company by depositing the proceeds
thereof in an account maintained and designated by the Company at an office or
branch of such Bank (or of an Affiliate of such Bank) located in the principal
financial center of the country issuing the Foreign Currency in which such
Borrowing is denominated or, if neither such Bank nor any Affiliate of such Bank
has an office or branch in such financial center, at such Bank's Eurodollar
Lending Office or Domestic Lending Office as selected by such Bank, or by such
other means requested by the Company and acceptable to such Bank. Promptly upon
any such disbursement of a Foreign Currency Bid-Option Loan, the Bank making
such Loan shall give written notice to the Agent by telex or telecopy of the
making of such Loan, which notice shall be substantially in the form attached
hereto as Exhibit H.

          (d)      If any Bank is to make a new Syndicated Loan or Dollar
Bid-Option Loan hereunder on a day on which the Company is to repay all or any
part of an outstanding Syndicated Loan or Dollar Bid-Option Loan from such Bank,
or if any Bank is to make a new Foreign Currency Bid-Option Loan hereunder on a
day on which the Company is to repay all or any part of an outstanding Foreign
Currency Bid-Option Loan of the same Foreign Currency from such Bank, such Bank
shall apply the proceeds of its new Loan to make such repayment and only an
amount equal to the difference, if any, between the amount of such new Loan and
the amount being repaid shall (i) be made available by such Bank to the Agent or
the Company, as provided in subsection (b) or (c) of this Section 3.5 or (ii) be
remitted by the Company to the Agent or such Bank as provided in Section 4.4, as
the case may be.  Except as provided in the first sentence of this Section
3.5(d), no Bank shall apply the proceeds of any Loan, whether a Foreign Currency
Bid-Option Loan or other type of Loan, to repay all or any part of an
outstanding Foreign Currency Bid-Option Loan, the entire amount of which shall,
unless repaid by the application of the proceeds of a new Foreign Currency
Bid-Option Loan of the same Foreign Currency as permitted in the first sentence
of this Section 3.5(d), be remitted in full by the Company to the Banks when due
as provided in Section 4.4.

     3.6     The Notes.

          (a)      The Syndicated Loans of each Bank shall be evidenced by a
single Syndicated Note payable to the order of such Bank in an amount equal to
the aggregate unpaid principal amount of such Bank's Syndicated Loans.

          (b)      The Bid-Option Loans of each Bank shall be evidenced by a
single Bid-Option Note payable to the order of such Bank in an amount equal to
the Dollar Equivalent of the aggregate unpaid principal amount of such Bank's
Bid-Option Loans.

          (c)      Upon receipt of each Bank's Notes pursuant to Section 8.2,
the Agent shall forward such Notes to such Bank.  Each Bank shall record on its
books and records, and prior to any transfer of its Notes shall endorse on the
schedules forming a part thereof appropriate notations to evidence, the date of
disbursement, amount and maturity of each Loan made by it, the interest rate and
Interest Period applicable thereto and the date and amount of each payment of
principal made by the Company with respect thereto.  Any notations made by such
Bank shall be prima facie evidence of the matters so recorded or endorsed.  Each
Bank is hereby irrevocably authorized by the Company to make such records, so to
endorse schedules to its Notes and to attach to and make a part of any  Note a
continuation of any such schedule as and when required. Failure by any Bank to
make such records or so to endorse the schedules to its Notes, or any error in
recording or so endorsing any such information, shall not affect the Company's
liability hereunder or under any Note.

     3.7     Certain Fees.

          (a)      Commitment Fees.  [Intentionally Omitted]

          (b)      Facility Fee.  The Company will pay to the Agent for the
respective accounts of the Banks a facility fee, for each calendar quarter or
portion thereof from the Closing Date to but not including the Termination Date,

period, at a rate equal to the Applicable Margin for Facility Fees.  All accrued
facility fees hereunder shall be payable in arrears with respect to each
calendar quarter or portion thereof not later than the tenth day after the end
of each March, June, September and December, commencing with the first such
calendar quarter-end after the Closing Date, and on the Termination Date.
Promptly upon receipt of such facility fees for any calendar quarter for portion
thereof, the Agent shall distribute such facility fees to the Banks ratably in
accordance with their respective Commitment Percentages.

          (c)      Closing Fee.  The Company will further pay to the Agent for
the respective accounts of the Banks such amount as may be agreed upon between
the Company and the Banks.  The closing fees shall be payable on or before the
Closing Date.  Promptly upon its receipt thereof, the Agent shall distribute
such fees to the Banks.

 (d)      Agent's Fees.  The Company will further pay to the Agent fees for its
own account for its services as Agent under this Agreement in such amounts and
at such times as may from time to time be agreed upon between the Company and
the Agent.

     3.8     Termination or Reduction of Commitments.

          (a)      Optional Termination or Reduction.  Subject to Section 5.5,
the Company shall have the right at any time and from time to time, upon five
Business Days' prior written notice to the Agent, to terminate or
proportionately reduce the amount of the Commitments, provided, that (i) any
partial reduction of the amount of the Commitments shall be in the amount of
$10,000,000 or a larger multiple thereof, (ii) no such reduction shall be
permitted with respect to any portion of the Commitments not in excess of the
sum of the Dollar Equivalent of the aggregate outstanding principal amount of
all Loans, plus the Letter of Credit Obligations Amount, plus the Dollar
Equivalent of the aggregate amount of all Borrowings for which a Notice of
Borrowing is then pending, plus the aggregate amount of all Letters of Credit
for which a Request for Letter of Credit Issuance is then pending, (iii) the
Commitments may not be terminated if any Loans or Letters of Credit are then
outstanding or any Notice of Borrowing or Request for Letter of Credit Issuance
is then pending and (iv) no such termination or reduction shall be permitted if,
after giving effect thereto, the Dollar Equivalent of the aggregate principal
amount of the outstanding Bid-Option Loans would exceed fifty percent (50%) of
the aggregate amount of the Commitments.  The Commitments or any portion thereof
terminated or reduced pursuant to this Section may not be reinstated.  The
accrued facility fees with respect to the terminated Commitments or the amount
of any reduction therein shall be payable on the effective date of such notice.
Upon receipt of any notice from the Company pursuant to this Section, the Agent
shall promptly notify each Bank of the contents thereof and of such Bank's share
of any reduction of the Commitments. Each such notice shall be irrevocable by
the Company once the Agent begins notifying any Bank of the contents thereof.

          (b)      [intentionally omitted].

          (c)      Section 4.2(d) Compliance.  On the effective date of any
reduction or termination of the Commitments under this Section 3.8, the Company
shall make such payments as may be required under Section 4.2(d) as a result
thereof.

     3.9     Mandatory Termination of Commitments.  The Commitments shall
terminate on the Termination Date.

     3.10    Extension of Scheduled Expiration Date.  (a) The Company may
request that the Banks extend the Scheduled Expiration Date from February 28,
2002 to February 28, 2003.  No such request shall be effective unless it is made
in writing by the Company at any time after February 28, 1999.

          (b)(i)  Upon receipt of any such written request, the Agent shall
promptly distribute a copy thereof to each Bank.

          (ii)  Each Bank shall have the time specified in such request to agree
or refuse to extend the Scheduled Expiration Date, which agreement or refusal,
as the case may be, must be communicated to the Agent in writing; provided, that
(A) the failure of any Bank so to communicate its agreement so to extend the
Scheduled Expiration Date shall be deemed to be such Bank's refusal so to
extend, (B) any written communication of any Bank of its agreement so to extend
shall be irrevocable and (C) any agreement of any Bank so to extend communicated
to the Agent subject to any qualifications or conditions shall be deemed to be a
refusal so to extend the Scheduled Expiration Date.


          (iii)  The Agent shall promptly notify the Company which Banks have
consented to such written request (a "Consenting Bank").  Any failure by the
Agent to so notify the Company shall not be deemed a consent to the Company's
request.

          (iv)      Each Bank that elects not to extend the requested Scheduled
Expiration Date or 


                      MASCOTECH, INC. CREDIT AGREEMENT

                                    -28-
<PAGE>   35

fails to so notify the Agent of such consent (a "Non-Consenting Bank")
hereby agrees that if any other Bank or financial institution acceptable to the
Company and the Agent offers to purchase such Non-Consenting Bank's
Commitment(s) for a purchase price equal to the sum of all amounts then owing
with respect to the Loans and all other amounts accrued for the account of such
Non-Consenting Bank and any amounts which may become owing as a result of such
purchase, such Non-Consenting Bank will, promptly or upon the existing
Scheduled Expiration Date for such Non-Consenting Bank, as elected by the
Company, assign, sell and transfer all of its right, title and obligations with
respect to the foregoing to such other Bank or financial institution pursuant
to and on the terms specified in the form of Assignment and Acceptance and
Section 11.6.

          (v)       Notwithstanding anything herein to the contrary, the
Scheduled Expiration Date will not be extended if the aggregate Commitments of
each Consenting Bank plus the additional Commitments of each Bank or other
financial institution replacing any Non-Consenting Bank pursuant to clause (iv)
above and agreeing to the request does not equal or exceed 75% of the then
existing aggregate Commitments.  If the Scheduled Expiration Date is extended
hereunder, it will not be extended for the Non-Consenting Banks whose
Commitments are not purchased pursuant to clause (iv) above, and each such
Non-Consenting Bank's Commitment shall remain in effect and not be terminated
until the Scheduled Expiration Date that is then in effect.

                                  ARTICLE IV.

                       PRINCIPAL PAYMENTS; INTEREST; ETC

     4.1     Scheduled Principal Payments. Unless earlier payment is required
under this Agreement, or made pursuant to Section 4.2, the Company shall pay the
entire principal amount of each Loan on the last day of the Interest Period
applicable to such Loan.

     4.2     Prepayments of Principal.  The following provisions apply in
respect of prepayment of the Loans by the Company:

     (a)     The Company may prepay Floating Rate Loans in whole or in part on
any Business Day in amounts aggregating $5,000,000 or any larger multiple of
$5,000,000 (unless such prepayment would cause the aggregate outstanding
principal amount of Floating Rate Loans to be less than $5,000,000, in which
event prepayment may only be made in an amount equal to the entire outstanding
principal amount of Floating Rate Loans), by paying the principal amount being
prepaid together with accrued interest thereon to the date of prepayment.  Each
prepayment in part of such Loans shall be applied to such Loans of the Banks
ratably in accordance with their respective shares of the aggregate outstanding
principal amount of the Floating Rate Loans.

     (b)     The Company may, upon at least three Business Days' notice to the
Agent, prepay any Fixed Base Rate Syndicated Borrowing in whole or in part on
any Business Day in the amount of $10,000,000 or any larger multiple of
$5,000,000 (unless such prepayment would cause the aggregate outstanding
principal amount of such Fixed Base Rate Syndicated Borrowing to be less than
$10,000,000, in which event prepayment may only be made in an amount equal to
the outstanding unpaid principal amount of such Fixed Base Rate Syndicated
Borrowing), by paying the principal amount being prepaid together with accrued
interest thereon to the date of prepayment; provided, however, that the Company
shall compensate the Banks pursuant to Section 5.5 for any losses or expenses
incurred as a result thereof.  Each prepayment in part of any Fixed Base Rate
Syndicated Borrowing shall be applied to the Fixed Base Rate Syndicated Loans
comprising such Borrowing of the Banks ratably in accordance with their
respective shares of the aggregate outstanding principal amount of such Loans.

<PAGE>   36

     (c)     Unless otherwise required by this Agreement, the Company may not
prepay any Bid-Option Loan in whole or in part without the consent of the Bank
that made such Bid-Option Loan.

     (d)     Notwithstanding SectionE4.2(a), (b) and (c), if on any date:

               (i) the sum of (A) the Dollar Equivalent of the aggregate
               outstanding principal amount of Loans plus (B) the Letter of
               Credit Obligations Amount exceeds the aggregate amount of the
               Commitments; or

               (ii) the Dollar Equivalent of the aggregate outstanding principal
               amount of Bid-Option Loans exceeds fifty percent (50%) of the
               Commitments; or

               (iii) the Dollar Equivalent of the aggregate outstanding
               principal amount of Foreign Currency Bid-Option Loans exceeds
               $50,000,000;


then the Company shall pay forthwith the principal amount of such excess,
together with accrued interest thereon to the date of payment; provided,
however, that the Company shall compensate the Banks pursuant to Section 5.5
for any losses or expenses incurred as a result thereof; and provided further,
however, that (A) no such payment otherwise required under clause (i) of this
Section 4.2(d) solely because of currency exchange rate fluctuations affecting
the Dollar Equivalent of the aggregate outstanding principal amount of Foreign
Currency Bid-Option Loans shall be required unless such payment is due on a
date when a payment of principal of any Loan is otherwise due hereunder, and
(B) notwithstanding clause (A) of this proviso, no such payment otherwise
required under subsection (ii) or (iii) of this Section 4.2(d) shall be
required if due solely because of currency exchange rate fluctuations affecting
the Dollar Equivalent of the aggregate outstanding principal amount of Foreign
Currency Bid-Option Loans since the last date on which any of such Foreign
Currency Bid-Option Loans were made.

     (e)     Upon receipt of a notice of prepayment pursuant to this Section,
the Agent shall promptly notify each Bank of the contents thereof and of such
Bank's share (in accordance with Section 4.4) of such prepayment. Each such
notice shall be irrevocable by the Company once the Agent begins notifying any
Bank of the contents thereof.

     4.3     Interest Payments.  The Company shall pay interest to the Banks on
the unpaid principal amount of each Loan, for the period commencing on the date
such Loan is made until such Loan is paid in full, on each Interest Payment Date
and at maturity (whether at stated maturity, by acceleration or otherwise), and
thereafter on demand, at the following rates per annum (subject, however, to the
provisions of Section 11.12):

     (a)     With respect to each Floating Rate Loan, at the Floating Rate.

     (b)     With respect to each CD Rate Loan, at the CD Rate, provided that if
any CD Rate Loan or any portion thereof shall, as a result of clause (b) of the
definition of CD Rate Interest Period, have an Interest Period of less than
thirty (30) days, such CD Rate Loan or portion thereof shall bear interest
during such Interest Period at the Floating Rate.

     (c)     With respect to each Eurodollar Rate Syndicated Loan, the
Syndicated Eurodollar Rate, provided that if any Eurodollar Rate Syndicated Loan
or any portion thereof shall, as a result of clause (c) of the definition of
Eurodollar Rate Interest Period, have an Interest Period of less than one month,
such Loan or portion thereof shall bear interest during such Interest Period at
the Floating Rate.



                      MASCOTECH, INC. CREDIT AGREEMENT

                                    -30-
<PAGE>   37


     (d)     With respect to each Eurodollar Rate Dollar Bid-Option Loan, the
Bid-Option Eurodollar Rate, provided that if any Eurodollar Rate Bid-Option Loan
or any portion thereof shall, as a result of clause (c) of the definition of
Eurodollar Rate Interest Period, have an Interest Period of less than one month,
such Loan or portion thereof shall bear interest during such Interest Period at
the Floating Rate.

     (e)     With respect to each Absolute Rate Dollar Bid-Option Loan and
Foreign Currency Bid-Option Loan, the Bid-Option Absolute Rate quoted for such
Loan by the Bank making such Loan.

Notwithstanding the foregoing subsections (a) through (e), the Company shall
(subject to the provisions of Section 11.12) pay interest on demand at the
Overdue Rate on the outstanding principal amount of any Loan and any other
amount payable by the Company hereunder (other than interest) which is not paid
in full when due (whether at stated maturity, by acceleration or otherwise) for
the period commencing on the due date thereof until the same is paid in full.

     4.4     Payment Procedures.

          (a)      All payments of any facility fees, closing fees, Letter of
Credit fees, Agent'sEfees, or other fees hereunder and of principal of, and
interest on, the Loans, other than Foreign Currency Bid-Option Loans, and of
reimbursement obligations in respect of Letters of Credit shall be made in
Dollars and in funds immediately available at the Agent'sEprincipal office in
Detroit, Michigan not later than 1:00 p.m. (Detroit time) on the date on which
such payment shall become due.  All payments of principal of, and interest on,
the Foreign Currency Bid-Option Loans shall be made in the currencies in which
such Loans are denominated and in funds immediately available, freely
transferable and cleared at the office or branch from which the Loan was made
under Section 3.5(c) not later than 3:00 p.m. local time on the date on which
such payment shall become due.  Promptly upon receipt of any payment of
principal of the Foreign Currency Bid-Option Loans the Bank receiving such
payment shall give written notice to the Agent by telex or telecopy of the
receipt of such payment, which notice shall be substantially in the form
attached hereto as ExhibitEI.  Whenever any payment of principal of, or interest
on, the Loans or of any fee shall be due on a day which is not a Business Day,
the date for payment thereof shall be extended to the next succeeding Business
Day (unless as a result thereof, in respect of Eurodollar Rate Loans, such date
would fall in the next calendar month, in which case it shall be advanced to the
next preceding Business Day) and, in the case of a payment of principal,
interest thereon shall be payable for any such extended time.

          (b)      Payments of principal of or interest on Existing Loans shall
be promptly distributed by the Existing Agent to each Existing Bank ratably in
proportion to each Existing Bank's Existing Commitment.  Payments of principal
of Syndicated Loans that comprise a Syndicated Borrowing, including any
Substitute Loan made by a Bank as part of any Fixed Base Rate Syndicated
Borrowing, shall be promptly distributed by the Agent to the Banks that made
such Syndicated Loans ratably in proportion to their respective shares of the
outstanding principal amount of such Syndicated Borrowing.  Payments of interest
on Syndicated Loans that comprise a Syndicated Borrowing, including any
Substitute Loan made by a Bank as part of any Fixed Base Rate Syndicated
Borrowing, shall be promptly distributed by the Agent to the Banks that made
such Syndicated Loans so that each such Bank receives a portion of such payment
equal to the amount of interest then owing to such Bank on such Loans multiplied
by a fraction, the denominator of which is the total amount of interest then
owing to all such Banks on such Loans and the numerator of which is the amount
of such payment.  Payments of principal of or interest on any Dollar Bid-Option
Loans that comprise a Dollar Bid-Option Borrowing shall be promptly distributed
by the Agent to the Banks that made such Dollar Bid-Option Loans ratably in
accordance with their respective Dollar Bid-Option Percentages.

          (c)      During any period when Dollar Bid-Option Loans are
outstanding, if the Agent cannot reasonably determine whether a particular
payment received by the Agent from the Company was 


                      MASCOTECH, INC. CREDIT AGREEMENT

                                    -31-
<PAGE>   38

intended to be applied to the principal of or interest on one or more
Dollar Bid-Option Borrowings or to the principal of or interest on Syndicated
Borrowings, or if the amount of any payment by the  Company is insufficient to
pay all amounts then due and payable with respect to Dollar Bid-Option Loans
and Syndicated Loans (including Substitute Loans), the Agent shall first
apportion such payment between the Dollar Bid-Option Loans and the Syndicated
Loans (including Substitute Loans) (i) if such payment is of principal, ratably
in accordance with the aggregate principal amount of each such type of Loans on
which payment is then due, and (ii) if such payment is of interest, ratably in
accordance with the aggregate amount of interest that is then due on each
such type of Loans.  After such apportionment, (i) the Agent shall distribute
the portion of the payment received and allocated to the Syndicated Loans
(including Substitute Loans) to the Banks as provided for payments of principal
of or interest on, as the case may be, Syndicated Loans under Section 4.4(b),
and (ii) the portion of the payment received and allocated to the Dollar
Bid-Option Loans on which a payment is then due shall first be allocated among
the different Dollar Bid-Option Borrowings of which such Dollar Bid-Option
Loans are a part (A) if such payment is of principal, ratably in accordance
with the aggregate principal amount of each such Dollar Bid-Option Borrowing,
and (B) if such payment is of interest, ratably in accordance with the
aggregate amount of interest that is then due on each such Dollar Bid-Option
Borrowing.  After such allocation, the Agent shall distribute the amount
allocated to each Dollar Bid-Option Borrowing to the Banks that made the Dollar
Bid-Option Loans comprising such Dollar Bid-Option Borrowing ratably in
accordance with their respective Dollar Bid-Option Percentages.

          (d)      Any prepayments of Bid-Option Loans made under Section 4.2(d)
may be applied to any one or more Bid-Option Borrowings as the Company may
select; provided that such payments shall be applied by the Agent, in the case
of Dollar Bid-Option Loans, or made directly by the Company, in the case of
Foreign Currency Bid-Option Loans, to the Banks participating in any such
Bid-Option Borrowing ratably in accordance with their respective Dollar
Bid-Option Percentages or Foreign Currency Bid-Option Percentages, as the case
may be.

     4.5     Computation of Interest and Fees.  Facility fees, Agent fees and
Letter of Credit fees, and interest on the Floating Rate Loans and other amounts
due hereunder, other than Fixed Rate Loans, shall be computed on the basis of a
year of 365 or 366 days, as the case may be, and actual days elapsed.  Interest
on the Fixed Rate Loans shall be computed on the basis of a year of 360 days and
actual days elapsed.

     4.6     No Setoff or Deduction.  All payments of principal of and interest
on the Loans and other amounts payable by the Company hereunder shall be made by
the Company without setoff or counterclaim, and free and clear of, and without
deduction or withholding for, or on account of, any present or future taxes,
levies, imposts, duties, fees, assessments, or other charges of whatever nature,
imposed by any governmental authority, or by any department, agency or other
political subdivision or taxing authority.

     4.7     Other Provisions Applicable to Foreign Currency Bid-Option Loans.
Foreign Currency Bid-Option Loans will be made by any Bank, if at all, in the
context of an international transaction, and the specification of payment in the
related Foreign Currency at a specific place pursuant to this Agreement is of
the essence.  Such Foreign Currency shall be the currency of account and payment
of such Loans under this Agreement and the Bid-Option Notes.  Notwithstanding
anything in this Agreement, the obligation of the Company in respect of such
Loans shall not be discharged by an amount paid in any other currency or at
another place, whether pursuant to a judgment or otherwise, to the extent the
amount so paid, on prompt conversion into the applicable Foreign Currency and
transfer to such Bank under normal banking procedure, does not yield the amount
of such Foreign Currency due under this Agreement and the Bid-Option Notes.  In
the event that any payment, whether pursuant to a judgment or otherwise, upon
conversion and transfer, does not result in payment of the amount of such
Foreign Currency due under this Agreement and the Bid-Option Notes, such Bank
shall have an independent cause of action against the Company for the currency
deficit.

                            CHANGE IN CIRCUMSTANCES

     5.1     Impossibility; Interest Rate Inadequate or Unfair.  (a) If before
the beginning of any Eurodollar Rate Interest Period or any CD Rate Interest
Period:

          (i) the Agent is advised by either Reference Bank that deposits
          in Dollars (in the applicable amounts) are not being offered to
          such Reference Bank in the relevant market for such Eurodollar
          Rate Interest Period or CD Rate Interest Period, as the case may
          be, or

          (ii)        the Required Banks advise the Agent that the
          Eurodollar Base Rate or the CD Base Rate will not adequately and
          fairly reflect the cost to such Banks of maintaining, making or
          funding, for such Eurodollar Rate Interest Period or CD Rate
          Interest Period, Eurodollar Rate Loans or CD Rate Loans, as the
          case may be, to which such Eurodollar Rate Interest Period or CD
          Rate Interest Period applies,

the Agent shall forthwith give notice thereof to the Company and the Banks,
whereupon until the Agent notifies the Company that the circumstances giving
rise to such suspension no longer exist, the obligations, if any, of the Banks
to make Eurodollar Rate Loans or CD Rate Loans, as the case may be, shall be
suspended.  In the case of Eurodollar Rate Loans, unless the Company notifies
the Agent (i) not later than 11:00 a.m. (Detroit time) on the second  Business
Day before the beginning of such Eurodollar Rate Interest Period that the
Company elects that the Borrowing shall be a CD Rate Borrowing or (ii) not
later than 3:00 p.m. (Detroit time) on the Business Day before the beginning of
such Eurodollar Rate Interest Period that the Company elects not to borrow on
such date, such Borrowing shall, subject to the provisions of Section 8.1, be a
Floating Rate Borrowing.  In the case of CD Rate Loans, unless the Company
notifies the Agent not later than 3:00 p.m. (Detroit time) on the first
Business Day before  the beginning of such CD Rate Interest Period that the
Company elects not to borrow on such date, such Borrowing shall, subject to the
provisions of Section 8.1, be a Floating Rate Borrowing.  Promptly after the
Agent receives any such notice from the Company under this Section 5.1(a), the
Agent shall notify each Bank of the contents thereof.  Any such notice from the
Company shall be irrevocable once the Agent begins notifying any Bank of the
contents thereof.

          (b)      If deposits in Dollars (in the applicable amounts) are not
being offered to a Reference Bank in the relevant market for any Eurodollar Rate
Interest Period or CD Rate Interest Period, by reason of circumstances affecting
such Reference Bank and not affecting the London or Nassau interbank market or
the United States market for certificates of deposit, as the case may be,
generally, the Agent shall, in consultation with the Company and with the
consent of the Required Banks, appoint another Bank to act as a Reference Bank
hereunder.

     5.2     Illegality.  If, after the date of this Agreement, the introduction
of, or any change in, any applicable law, rule or regulation or in the
interpretation or administration thereof by any governmental authority
charged with the interpretation or administration thereof or compliance by any
Bank (or its Applicable Lending Office) with any request or directive (whether
or not having the force of law) of any such authority shall make it unlawful or
impossible for such Bank (or its Applicable Lending Office) to honor its
binding legal obligations, if any, hereunder to make, maintain or fund any type
of Fixed Rate Loans, such Bank shall so notify the Agent, and the Agent shall
forthwith give notice thereof to the Company, whereupon until such Bank
notifies the Agent that the circumstances giving rise to such suspension no
longer exist, the 




                      MASCOTECH, INC. CREDIT AGREEMENT

<PAGE>   40

obligation, if any, of such Bank to make such type of Fixed Rate Loans
shall be suspended.  Before any Bank gives any notice of unlawfulness or
impossibility to the Agent under this Section 5.2, such Bank shall designate a
different Applicable Lending Office if such designation will avoid the need for
giving such notice and will not, in the judgment of such Bank, be otherwise
disadvantageous to such Bank.  Upon receipt of such notice, the Company shall
prepay in full the then outstanding principal amount of each affected Fixed
Rate Loan of such Bank together with accrued interest thereon (a) on the last
day of the then current Interest Period applicable to such Loan if such Bank
may lawfully continue to maintain and fund such Loan to such day, or (b)
immediately if such Bank may not lawfully continue to fund and maintain such
Loan to such day.  Concurrently with prepaying each such Fixed Rate Loan, the
Company shall borrow a Floating Rate Loan (or, if the Company so elects by at
least three Business Days' notice to the Agent and such Bank, a Fixed Base Rate
Syndicated Loan of an unaffected type) in an equal principal amount from such
Bank, for an Interest Period coinciding with the remaining term of the Interest
Period applicable to such Fixed Rate Loan, and such Bank shall make such a
Loan, provided that there has been no acceleration of the amounts due under the
Notes pursuant to Article IX.

     5.3     Increased Cost; Yield Protection.

          (a)      If, after the date hereof, the introduction of, or any change
in, any applicable law, treaty, rule or regulation (whether domestic or foreign
and including, without limitation, the Federal Deposit Insurance Act, as
amended, and Regulation D of the Board of Governors of the Federal Reserve
System) or in the interpretation or administration thereof by any governmental
authority, central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by any Bank (or its Applicable Lending
Office) with any request or directive of any such authority, central bank or
comparable agency (whether or not having the force of law),

          (i) shall subject any Bank (or its Applicable Lending Office) to any
          tax, duty or other charge with respect to its obligation to make any
          Loans, its Notes, any of its Loans or any of the Letters of Credit or
          shall change the basis of taxation of payments to any Bank (or its
          Applicable Lending Office) of the principal of or interest on any of
          its Fixed Rate Loans or in respect of its obligation, if any, to make
          any Loans or to participate in the risk of Letters of Credit (except
          for changes in the rate of tax on the overall net income of such Bank
          or its Applicable Lending Office imposed by the jurisdiction in which
          such Bank's principal executive office or Applicable Lending Office is
          located), or

          (ii)    shall impose, modify or deem applicable any reserve
          (including, without limitation, any imposed by the Board of Governors
          of the Federal Reserve System, but excluding (A) with respect to any
          CD Rate Loan any reserve requirements to the extent included in 
          clause (ii) of subpart (a) of the definition of CD Base Rate when 
          calculating the CD Base Rate with respect to such CD Rate Loan, 
          and (B) with respect to any Eurodollar Rate Loan any reserve 
          requirements to the extent included in clause (b) of the definition 
          of Eurodollar Base Rate when calculating the Eurodollar Base 
          Rate with respect to such Eurodollar Rate Loan), special deposit
          or similar requirement (including, without limitation, any deposit

          make Loans or to participate in the risk of Letters of Credit or
          affecting its Loans or the Letters of Credit or affecting the
          Company's obligations under the Notes in respect of such Loans,


and the result of any of the foregoing is to increase the cost to such Bank (or
its Applicable Lending Office) of making or maintaining its existing or future
Fixed Rate Loans or of participating in the risk of Letters of Credit, or to
reduce the amount of any sum received or receivable by such Bank (or its
Applicable Lending Office) under this Agreement or under the Notes (in respect
of Fixed Rate Loans or Letters of Credit) by an amount deemed by such Bank to
be material, then such Bank may notify the Company (with a copy of any such
notice to be provided to the Agent) of any such fact of which it has knowledge
and demand compensation therefor; provided that, if such Bank fails to demand
such compensation (or notify the Company that it will or may demand such
compensation) promptly upon becoming aware of the facts entitling it to do so
or, if such Bank is contesting the cause of such increased cost or reduced sum
received or receivable, promptly after the earlier of (A) the final
determination of such contest or (B) an officer of such Bank who is responsible
for the administration of the credit outstanding under this Agreement from such
Bank to the Company becoming aware of such facts, such Bank shall not be
entitled to such compensation for the period before the date on which it
actually demands (or notifies the Company that it will or may demand) such
compensation; provided, further, that if such Bank is contesting the cause of
such increased cost or reduced sum received or receivable, such Bank shall not
in any event be entitled to such compensation for any period prior to six
months before it notifies the Company that such Bank may or will demand such
compensation.  The Company agrees to pay to such Bank such additional amount or
amounts as will compensate such Bank for such increased cost or reduction
within 15 days after demand by such Bank.  A certificate of such Bank setting
forth the basis for determining such additional amount or amounts necessary to
compensate such Bank shall be conclusive in the absence of manifest error.
Each such Bank will designate a different Applicable Lending Office if such
designation would avoid the need for, or reduce the amount of such compensation
and would not, in the judgment of such Bank, be otherwise disadvantageous to
such Bank.  In the event that the Company is required to compensate any Bank
for any increased cost to such Bank pursuant to this Section 5.3(a), the
Company shall have the right, upon at least five Business Days' prior notice to
such Bank through the Agent, to prepay in full any outstanding Fixed Rate Loans
that are related to such increased cost of such Bank, together with accrued
interest thereon to the date of prepayment; provided that prepayment of 
such Fixed Rate Loans shall not relieve the Company of its obligation 
to compensate such Bank in accordance with this Section 5.3(a), the amount 
of which compensation shall be due at the time of such prepayment,
notwithstanding any other provision of this Section 5.3(a).  Concurrently with
prepaying each such Fixed Rate Loan of such Bank, the Company shall borrow a
Floating Rate Loan (or, if the Company shall so elect in its notice of
prepayment, a Fixed Rate Loan of another type) in an equal principal amount
from such Bank for an Interest Period coinciding with the remaining term of the
Interest Period applicable to such Fixed Rate Loan, and such Bank shall make
such a Floating Rate Loan (or Fixed Rate Loan of the other type), provided that
there has been no acceleration of the amount due under the Notes pursuant to
Article IX.  The Company shall pay compensation owing to any Bank(s) under this
Section 5.3(a) notwithstanding any subsequent replacement (pursuant to Section
11.13) of the Bank(s) making demand for such compensation.

          (b)      In the event that any applicable law, treaty, rule or
regulation (whether domestic or foreign) now or hereafter in effect and whether
or not presently applicable to any Bank or the Agent, or any interpretation or
administration thereof by any governmental authority charged with the
interpretation or administration thereof, or compliance by any Bank or the Agent
with any guideline, request or directive of any such authority (whether or not
having the force of law), including any risk-based capital guidelines, affects
or would affect the amount of capital required or expected to be maintained by
such Bank or the Agent (or any corporation controlling such Bank or the Agent)
and such Bank or the Agent, as the case may be, determines that the amount of
such capital is increased by or based upon the existence of such Bank's or the
Agent's 


                      MASCOTECH, INC. CREDIT AGREEMENT


                                    -35-

obligations or Loans hereunder and such increase has the effect of
reducing the rate of return on such Bank's or the Agent'sE(or such controlling
corporation's) capital as a consequence of such obligations or Loans hereunder
to a level below that which such Bank or the Agent (or such controlling
corporation) could have achieved but for such circumstances (taking into
consideration its policies with respect to capital adequacy) by an amount deemed
by such Bank or the Agent to be material, then such Bank or the Agent may notify
the Company of any such fact of which it has knowledge and the Company shall pay
to such Bank or the Agent, as the case may be, from time to time, upon request
by such Bank (with a copy of such request to be provided to the Agent) or the
Agent, additional amounts sufficient to compensate such Bank or the Agent (or
such controlling corporation) for any increase in the amount of capital and
reduced rate of return which such Bank or the Agent reasonably determines to be
allocable to the existence of such Bank's or the Agent'sEobligations or Loans
hereunder; provided that, if such Bank or the Agent fails to notify the Company
of any such fact promptly upon becoming aware thereof or, if such Bank or the
Agent is contesting the cause of such increase in the amount of capital or
reduced rate of return, promptly after the earlier of (A) the final
determination of such contest or (B) an officer of such Bank who is responsible
for the administration of the credit outstanding under this Agreement from such
Bank to the Company becoming aware of any such fact, such Bank or the Agent, as
the case may be, shall not be entitled to such compensation for the period
before the date on which it actually notifies the Company of such fact;
provided, further, that if such Bank or the Agent is contesting the cause of
such increase in the amount of capital or reduced rate of return, such Bank or
the Agent, as the case may be, shall not in any event be entitled to such
compensation for any period prior to six months before it notifies the Company
that such Bank or the Agent, as the case may be, may or will demand such
compensation.  A statement as to the amount of such compensation, prepared in
good faith and in reasonable detail by such Bank or the Agent, as the case may
be, and submitted by such Bank or the Agent to the Company, shall be conclusive
in the absence of manifest error in computation. The Company shall pay such
compensation for the periods covered by such notice notwithstanding any
replacement (pursuant to Section 11.13) of the Bank(s) making demand for such
compensation.

     5.4     Substitute Loans.  If (a) the obligation, if any, of any Bank to
make any type of Fixed Rate Loans has been suspended pursuant to Section 5.2 or
(b) any Bank has demanded compensation under Section 5.3(a) and the Company
shall, by at least five Business Days' prior notice to such Bank through the
Agent, have elected that the provisions of this Section 5.4 shall apply to such
Bank, then, unless and until such Bank notifies the Company that the
circumstances giving rise to such suspension or demand for compensation no
longer apply:

          (i) all Loans which would otherwise be made by such Bank as the
     affected type of Fixed Rate Loans shall be made instead as Floating Rate
     Loans, or if the Company shall so elect in the Notice of Borrowing, another
     type of Fixed Rate Loan (whichever type is not affected by such
     circumstances) for an Interest Period coincident with the related Fixed
     Rate Borrowing, and

          (ii)    after each of its affected Fixed Rate Loans has been repaid,
     all payments of principal which would otherwise be applied to repay such
     Fixed Rate Loans shall be applied to repay its Substitute Loans instead.

     5.5     Funding Losses.  If the Company makes any payment of principal with
respect to any Fixed Rate Loan on any other date than the last day of an
Interest Period applicable thereto (whether pursuant to Section 3.8, 4.2, 5.1,
5.2, 5.3 or 5.4, Article IX or otherwise), or if the Company fails to borrow any
Fixed Rate Loan after the related Notice of Borrowing has been given to the
Agent, or if the Company fails to make any payment of principal or interest in
respect of a Fixed Rate Loan when due, the Company shall reimburse each Bank on
demand for any resulting loss or expense incurred by such Bank, including
without limitation any loss incurred in obtaining, liquidating or employing
deposits from third parties, whether or not such Bank shall have funded or
committed to fund such Loan.  A statement as to the amount of such loss or
expense, prepared in good faith and in reasonable detail by such Bank and
submitted by such Bank to the Company, 


                      MASCOTECH, INC. CREDIT AGREEMENT


                                    -36-
<PAGE>   43

shall be conclusive and binding for all purposes absent manifest error
in computation.  Calculation of all amounts payable to each Bank under this
Section 5.5 shall be made as though such Bank shall have actually funded or
committed to fund the relevant Fixed Rate Loan through the purchase of an
underlying deposit in an amount equal to the amount of such Loan and having a
maturity comparable to the related Interest Period; provided, however, that
such Bank may fund any Fixed Rate Loan in any manner it sees fit and the
foregoing assumption shall be utilized only for the purpose of calculation of
amounts payable under this Section 5.5.

                                  ARTICLE VI.

                         REPRESENTATIONS AND WARRANTIES

     The Company hereby represents and warrants to the Agent and the Banks that:

     6.1     Corporate Existence and Power.  Each of the Company and its
Domestic Subsidiaries is a corporation duly incorporated, validly existing and
in good standing under the laws of the State of its incorporation, and is duly
qualified as a foreign corporation in each State or other jurisdiction in the
United States of America in which the conduct of its operations or the ownership
of its properties requires such qualification and failure so to qualify would
materially and adversely affect the Company and its Subsidiaries taken as a
whole.  All of such corporations have all requisite corporate power to own their
properties and to carry on their businesses, considered as a whole,
substantially as now owned and as now being conducted.  The Company has full
power, authority and legal right to execute and deliver this Agreement and the
Notes, to perform and observe the terms and provisions hereof and thereof, and
to borrow hereunder.

     6.2     Corporate Authority; No Violations; Governmental Filings; Etc. The
execution, delivery and performance by the Company of this Agreement, the
issuance of the Notes and the borrowings hereunder have been duly authorized by
all necessary corporate action and do not and will not violate the provisions of
any applicable law or regulation or of the certificate of incorporation or
by-laws of the Company or any Subsidiary or any order of any court, regulatory
body or arbitral tribunal and do not and will not result in the breach of, or
constitute a default or require any consent under, or create any lien, charge or
encumbrance upon any property or assets of the Company or any Subsidiary
pursuant to, any indenture or other agreement or instrument to which the Company
or any Subsidiary is a party or by which the Company or any Subsidiary or its
property may be bound or affected.  Neither the execution, delivery and
performance of this Agreement nor the issuance of the Notes nor any borrowing
hereunder requires, for the validity thereof, nor does the enforceability of
this Agreement or any of the Notes require, any filing with, or consent,
authorization  or approval of, any state or federal agency or regulatory
authority, other than filings, consents or approvals which have been made or
obtained or which, in the case of any such borrowing, will be made or obtained
prior to the due date for such filing, consent or approval.

     6.3     Binding Effect.  This Agreement constitutes, and the Notes when
executed and delivered by the Company for value will constitute, the legal,
valid and binding obligations of the Company, enforceable against the Company in
accordance with their respective terms.

     6.4     Litigation.  There are no suits, proceedings, or actions at law or
in equity or by or before any governmental commission, board, bureau, or other
administrative agency, pending or, to the knowledge of the Company, threatened
against the Company or any of its Subsidiaries or affecting the Company or any
of its Subsidiaries, which, in the reasonable opinion of the Company, either (i)
are likely to have a material adverse effect on the financial condition or
business of the Company and its Subsidiaries taken as a whole or (ii) will in
any manner affect the enforceability or validity of this Agreement or any Note.

<PAGE>   44


     6.5     Taxes.  The Company and each Subsidiary has filed (or has obtained
extensions of the time by which it is required to file) all United
States federal income tax returns, and all other tax returns which are required
to be filed and are material to the business, operations or financial position
of the Company and its Subsidiaries taken as a whole, and has paid all taxes
shown due pursuant to such returns or pursuant to any assessment received by
the Company or any Subsidiary, except such taxes, if any, as are being
contested in good faith and as to which, in the reasonable opinion of the
Company, adequate reserves have been provided in accordance with generally
accepted accounting principles.  The Company does not know of any proposed tax
assessment against it or any Subsidiary or of any basis for one, except to the
extent any such assessment has been, in the reasonable opinion of the Company,
adequately provided for in the consolidated tax reserves of the Company and its
Subsidiaries in accordance with generally accepted accounting principles.

     6.6     Financial Condition.  The consolidated balance sheet of the Company
and its Consolidated Subsidiaries and consolidated statements of income,
shareholders' equity and cash flows of the Company and its Consolidated
Subsidiaries for the fiscal year ended December 31, 1995, certified by Coopers &
Lybrand, independent certified public accountants, and the interim unaudited
consolidated balance sheet and interim unaudited consolidated statements of
income, shareholders' equity and cash flows of the Company and its Consolidated
Subsidiaries, as of or for the nine-month period ended on September 30, 1996,
copies of which have been furnished to the Banks, fairly present the
consolidated financial position of the Company and its Consolidated Subsidiaries
as at the dates thereof, and the consolidated results of operations of the
Company and its Consolidated Subsidiaries for the respective periods indicated,
all in accordance with generally accepted accounting principles consistently
applied (except as disclosed in the notes thereto and subject, in the case of
interim statements, to year-end audit adjustments). Except as disclosed in the
financial statements as of or for the nine-month period ended September 30,
1996, there has been no material adverse change in the consolidated operations
or condition, financial or otherwise, of the Company and its Consolidated
Subsidiaries considered as a whole, since December 31, 1995.

     6.7     Compliance with ERISA.  Each of the Company and each ERISA
Affiliate of the Company (a) has fulfilled its obligations under the minimum
funding standards of ERISA and the Code with respect to each Plan and (b) is in
compliance in all material respects with the presently applicable provisions of
ERISA and the Code with respect to each Plan.  Neither the Company nor any ERISA
Affiliate of the Company has (x) sought a waiver of the minimum funding standard
under Section 412 of the Code in respect of any Plan, (y) failed to make any
contribution or payment to any Plan or Multiemployer Plan or in respect of any
Benefit Arrangement, or made any amendment to any Plan or Benefit Arrangement,
which has resulted or could result in the imposition of a Lien or the posting of
a bond or other security under ERISA or the Code, in each case securing an
amount greater than $10,000,000, or (z) incurred any liability under Title IV of
ERISA, other than a liability to the PBGC for premiums under Section 4007 of
ERISA, which could materially adversely affect the business, consolidated
financial position or consolidated results of operations of the Company and its
Consolidated Subsidiaries.

     6.8     Environmental Matters.  In the ordinary course of its business, the
Company conducts appropriate reviews of the effect of Environmental Laws on the
business, operations and properties of the Company and its Subsidiaries, in the
course of which it identifies and evaluates pertinent liabilities and costs
(including, without limitation, capital or operating expenditures required for
clean-up or closure of properties presently or previously owned or for the
lawful operation of its current facilities, required constraints or changes in
operating activities, and evaluation of liabilities to third parties, including
employees, together with





                        MASCOTECH, INC. CREDIT AGREEMENT


                                      -38-



<PAGE>   45


pertinent costs and expenses).  On the basis of this review, the Company has
reasonably concluded that Environmental Laws are not likely to have a material
adverse effect on the business, financial position or results of operations of
the Company and its Consolidated Subsidiaries, considered as a whole.

     6.9     Compliance with Laws.  The Company complies, and has caused each
Subsidiary to comply, in all material respects with all applicable laws,
ordinances, rules, regulations, and requirements of governmental authorities
(including, without limitation, Environmental Laws and ERISA and the rules and
regulations thereunder), except where (a) the necessity of compliance therewith
is contested in good faith by appropriate proceedings and the Company has
established appropriate reserves for liability for noncompliance therewith in
accordance with generally accepted accounting principles, (b) no officer of the
Company is aware that the Company or the relevant Subsidiary has failed to
comply therewith, or (c) the Company has reasonably concluded that failure to
comply is not likely to have a material adverse effect on the business,
financial position or results of operations of the Company and its Consolidated
Subsidiaries, taken as a whole.


                                  ARTICLE VII.

                                   COVENANTS

     Until all the Commitments and Letters of Credit have expired or been
terminated and all Loans and reimbursement and other obligations of the Company
hereunder have been paid in full, the Company covenants that:

previous fiscal year and ending with the end of such quarter, setting forth in
each of the statements required by this subsection (a), in comparative form,
corresponding figures as of the end of and for the corresponding period of the

all in reasonable detail and certified without material qualifications by
Coopers & Lybrand, or by other independent certified public accountants of
recognized national standing selected by the Company and reasonably acceptable
to the Agent;

          (c)      as soon as practicable and in any event within 30 days after
the sending or filing thereof, copies of all such financial statements and
reports as it shall send to its security holders and of all final prospectuses
under the Securities Act of 1933 (other than form S-8), reports on forms 10-Q,
10-K and 8-K and all similar regular and periodic reports filed by it (i) with
any federal department, bureau, commission or agency from time to time having
jurisdiction with respect to the sale of securities or (ii) with any securities
exchange;

          (d)      if and when the Company or any ERISA Affiliate of the Company
(i) gives or is required to give notice to the PBGC of any "reportable event"
(as defined in Section 4043 of ERISA) with

Plan has given or is required to give notice of any such reportable event, a
copy of the notice of such reportable event given or required to be given to
the PBGC; (ii) receives notice of complete or partial withdrawal liability

to make any payment or contribution to any Plan or Multiemployer Plan or in

Benefit Arrangement which has resulted or could result in the imposition of a
Lien or the posting of a bond or other security, a certificate of the chief
financial officer or the chief accounting officer of the Company setting forth
details as to such occurrence and action, if any, which the Company or
applicable ERISA Affiliate is required or proposes to take; provided that no
such certificate shall be required unless the aggregate unpaid actual or
potential liability of the Company and the ERISA Affiliates involved in all
events referred to in clauses (ii) through (vii) above of which officers of the
Company have obtained knowledge and have not previously reported under this
subparagraph (d) exceeds $15,000,000; and

          (e)      with reasonable promptness, such other information regarding
the financial condition of the Company or any of its Subsidiaries as any Bank
may from time to time reasonably request.

     7.2     Certificates of No Default and Compliance.

          (a)      Concurrently with each delivery of the financial statements
pursuant to subsections (a) and (b) of Section 7.1, the Company will deliver to
the Agent (with a copy delivered to each Bank) a certificate, signed by the
chief accounting officer or chief financial officer of the Company (i) stating
that to the best of his knowledge after due inquiry, at the date of such
financial statements no Default had occurred and was continuing, or, if a
Default had occurred and was continuing, specifying the nature and period of
existence thereof and what action the Company has taken or proposes to take with
respect thereto; and (ii) setting forth as of the date of such financial
statements, in reasonable detail, the calculations employed to determine
compliance with Sections 7.5, 7.7, 7.8 and 7.9 and an explanation in reasonable
detail of any differences between generally accepted accounting principles as
then in effect and generally accepted accounting principles used in making such
calculations, as may be permitted under Section 1.2. The certificate will be
accompanied by a calculation of the ratio of (i) Senior Debt as of the end of
such fiscal quarter to (ii) EBITDA Minus Capital Expenditures as of the end of
such fiscal quarter (calculated on a pro forma basis as appropriate).

          (b)      Within 60 days after the end of each fiscal quarter of each
fiscal year of the Company (including the last fiscal quarter of each such
fiscal year), the Company will deliver to the Agent (with a copy delivered to
each Bank) a certificate, signed by the chief accounting officer, chief
financial officer, treasurer or assistant treasurer of the Company, setting
forth in reasonable detail the calculation of the Senior Leverage Ratio and the
Interest Coverage Ratio, as of the Determination Date and for the Determination
Period, respectively, with respect to the next forthcoming Application Period,
and identifying the Applicable Margin for such Application Period as a result of
such calculations.

          (c)      Within fifteen Business Days after any officer of the Company
obtains knowledge of a Default, the Company will, unless the same shall have
been cured within such fifteen Business Day period, give written notice to each
of the Banks thereof, specifying the nature thereof, the period of existence
thereof and what action the Company proposes to take with respect thereto.

     7.3     Preservation of Corporate Existence, Etc. The Company will preserve
and maintain its corporate existence, and qualify and remain qualified as a
validly existing corporation in good standing in each jurisdiction in which the
conduct of its operations or the ownership of its properties requires such

the Company and its Subsidiaries taken as a whole.

     7.4     Current Ratio.  [Intentionally Omitted]

     7.5     Total Leverage Ratio. The Company will not permit or suffer the

Debt Coverage Ratio to be greater than the Maximum Allowed Senior Debt Coverage
Ratio as of the Relevant Days immediately following both of such fiscal
quarters.

          (c)      As used in this Section 7.8, the term "Maximum Allowed Senior

     7.10    Negative Pledge.  Neither the Company nor any Consolidated
Subsidiary will create, assume or suffer to exist any Lien on any asset now
owned or hereafter acquired by it, except:

          (a) Liens existing on the date of this Agreement securing Debt
     outstanding on the date of this Agreement in an aggregate principal amount
     not exceeding $25,000,000;

          (b) any Lien existing on any asset of any corporation at the time such
     corporation becomes a Consolidated Subsidiary and not created in
     contemplation of such event;

          (c) any Lien on any asset securing Debt incurred or assumed for the
     purpose of financing all or any part of the cost of acquiring such asset
     (or acquiring a corporation or other entity which owned such asset),
     provided that such Lien attaches to such asset concurrently with or within
     90 days after such acquisition;

          (d) any Lien on any asset of any corporation existing at the time such
     corporation is merged or consolidated with or into the Company or a
     Consolidated Subsidiary and not created in contemplation of such event;

          (e) any Lien existing on any asset prior to the acquisition thereof by
     the Company or a Consolidated Subsidiary and not created in contemplation
     of such acquisition;

          (f) any Lien arising out of the refinancing, extension, renewal or
     refunding of any Debt secured by any Lien permitted by any of the foregoing
     clauses of this Section, provided that such Debt is not increased and is
     not secured by any additional assets;

          (g) any Lien in favor of the holder of Debt (or any Person acting for
     or on behalf of such holder) arising pursuant to any order of attachment,
     distraint or similar legal process arising in connection with court
     proceedings so long as the execution or other enforcement thereof is
     effectively stayed and the claims secured thereby are being contested in
     good faith by appropriate proceedings and the Company or such Consolidated
     Subsidiary, as the case may be, has established appropriate reserves
     against such claims in accordance with generally accepted accounting
     principles;

          (h) Liens incidental to the normal conduct of its business or the
     ownership of its assets which (i) do not secure Debt and (ii) do not in the
     aggregate materially detract (due to the amount of the liability secured by
     such Liens or otherwise) from the value of the assets of the Company and
     the Company's Consolidated Subsidiaries taken as a whole or in the
     aggregate materially impair the use thereof in the operation of the
     business of the Company and the Company's Consolidated Subsidiaries taken
     as a whole; and

          (i) Liens not otherwise permitted by the foregoing clauses of this
     Section; provided that (i) the aggregate outstanding principal amount of
     Debt secured by all such Liens on Current Assets shall not at any time
     exceed 20% of Current Assets and (ii) the aggregate outstanding principal
     amount of Debt secured by all such Liens (including Liens referred to in
     clause (i) of this proviso) shall not at any time exceed the sum of 5% of
     Net Worth plus 20% of Current Assets, provided, further, that for purposes
     of this Section 7.10(i), Current Assets shall not include any assets that
     are classified as Current Assets solely because they are held for sale;

provided, however, that the restrictions set forth in this Section 7.10 shall
not apply to "margin stock" (as defined in Regulation U of the Board of
Governors of the Federal Reserve System), if and to the extent that the value
of the margin stock with respect to which the rights of the Company and its
Subsidiaries are

continuing or surviving corporation of such merger or consolidation.

Consolidated Subsidiaries in the twelve months then ended would exceed 15% of
the total assets of the Company and its Consolidated Subsidiaries as shown on
the most recent balance sheet delivered to the Banks under Section 7.1;
provided, for purposes of this Section 7.11(b), the aggregate amount of assets
disposed of in all Restricted Transfers by the Company and the Consolidated
Subsidiaries prior to the Closing Date shall be deemed to be equal to zero.  For
purposes of this subsection (b), the term "Restricted Transfer" means a direct
or indirect sale, lease, transfer or other disposition of assets (other than
cash, margin  stock, or the sale of inventory in the ordinary course of
business) to any Person (other than the Company or a Substantially-Owned

transaction (and as a substantial part of the consideration incident thereto),
the Company or any Consolidated Subsidiary receives an equity ownership interest
in such Person or any right to receive payments which are specifically
contingent in amount or duration upon the earnings of such Person or any portion
of such Person's business.

          (c)      Notwithstanding any other provision of this Section 7.11, no
disposition of assets, merger, consolidation or Restricted Transfer referred to
in subsection (a) or (b) of this Section shall be permitted if, immediately
after giving effect thereto, any Default would exist.

     7.12    Changes in Subordinated Debt. The Company will not (a) transfer,
convey, assign or deliver to any holder of any Subordinated Debt, or to any
trustee, paying agent or other fiduciary for the benefit of the holder of any
Subordinated Debt (including any defeasance), any cash, securities (other than
securities constituting Subordinated Debt) or other assets of the Company or any
Subsidiary in payment or on account of, or as provision for, principal, premium,
if any, or interest on any Subordinated Debt which is not required under the
instruments and agreements relating to such Subordinated Debt (provided that any
payment which is blocked by any creditors of the Company or any of its
Subsidiaries pursuant to the terms of the applicable instrument or agreement
shall not be deemed to be required) or (b) or amend, modify or waive any term or
provision of any instrument or agreement relating to any Subordinated Debt such
that it would not constitute "Subordinated Debt" as defined herein if (i) at the
time of any such transfer, conveyance, assignment, delivery, amendment,
modification or waiver there shall exist and be continuing, or if immediately
after giving effect thereto as a reasonably foreseeable result thereof on a pro
forma basis there would exist or would be caused thereby, an Event of Default or
Default, or (ii) unless the Agent is given at least five (5) Business Days (or
such shorter period of time acceptable to the Agent) prior notice thereof, any
such transfer, conveyance, assignment or delivery is made more than seven (7)
days in advance of a scheduled payment or prepayment on any Subordinated Debt or
in an amount in excess of the amount of such scheduled payment or prepayment.

     7.13    Use of Proceeds.  None of the proceeds of the Loans made under this
Agreement will be used in violation of any applicable law or regulation
including, without limitation, Regulation U of the Board of Governors of the
Federal Reserve System.

Subsidiary to comply, in all material respects with all applicable laws,
ordinances, rules, regulations, and requirements of governmental authorities
(including, without limitation, Environmental Laws and ERISA and the rules and
regulations thereunder) except where (a) the necessity of compliance therewith
is contested in good faith by appropriate proceedings, (b) no officer of the
Company is aware that the Company or the relevant Subsidiary has failed to
comply therewith or (c) the Company has reasonably concluded that failure to
comply is not likely to have a material adverse effect on the business,
financial position or results of operations of the Company and its Consolidated
Subsidiaries, taken as a whole.

     such holder or holders) thereof or of any obligations issued thereunder to
     accelerate the maturity thereof or of any such obligations in an aggregate
     principal amount in excess of $5,000,000, and such failure has not been

     approval or consent of the Company or any Significant Subsidiary in any
     court of competent jurisdiction seeking, in respect of the Company or such

     Closing Date and each other director, if such other director's nomination
     for election to the Board of Directors of the Borrower is recommended by a
     majority of the then Continuing Directors;

then, and in each such case, the Agent may and, upon being directed to do so by
the Required Banks, shall, by written notice to the Company, (i) immediately
terminate the Commitments, (ii) declare the principal of and interest accrued
on all the Notes, all unpaid reimbursement obligations in respect of drawings

of the occurrence of any event described in the foregoing clauses (f) and (g)
the Commitments shall automatically terminate forthwith and all such amounts,
including such cash collateral, shall automatically become immediately due and
payable without action upon the part of the Required Banks and without the
requirement of any such notice, and without presentment, demand, protest or
other notice of any kind, all of which are hereby waived.  Such cash collateral
delivered in respect of outstanding Letters of Credit shall be deposited in a
special cash collateral account to be held by the Agent as collateral security
for the payment and performance of the Company's obligations under this
Agreement and the Notes to the Banks and the Agent.

     9.2     Remedies.  The Agent may and, upon being directed to do so by the

law, in any manner deemed appropriate by the Agent, including suit in equity,
action at law, or other appropriate proceedings, whether for the specific
performance (to the extent permitted by law) of any covenant or agreement
contained in this Agreement or in the Notes or in aid of the exercise of any
power granted in this Agreement or the Notes.

     9.3     Set Off.  Upon the failure of the Company to pay any indebtedness
under this Agreement or the Notes at its maturity (whether at stated maturity,
by acceleration or otherwise) or, in the case of such indebtedness other than
principal of the Loans, when due (after allowing for any grace period provided
with respect thereto under Section 9.1(a)), each Bank may at any time and from
time to time, without notice to the Company (any requirement for such notice
being expressly waived by the Company) set off and apply against any and all of
the obligations of the Company now or hereafter existing under this Agreement
and the Notes, whether owing to such Bank or any other Bank or the Agent, any
and all deposits (general or special, time or demand, provisional or final) at
any time held and other indebtedness at any time owing by such Bank to or for
the credit or the account of the Company and any property of the Company from
time to time in possession of such Bank, regardless of whether or not such Bank
shall have made any demand hereunder or any indebtedness owing by such Bank may
be contingent and unmatured.  The rights of the Banks under this Section 9.3 are
in addition to other rights and remedies (including, without limitation, other
rights of setoff) which the Banks may have.

                                   ARTICLE X.

                            THE AGENTS AND THE BANKS

     10.1    Appointment and Authorization.  Each Bank hereby irrevocably
appoints and authorizes the Agent to take such action as agent on its behalf and
to exercise such powers under this Agreement and the Notes as are delegated to
the Agent by the terms hereof or thereof, together with all such powers as are
reasonably incidental thereto.  The provisions of this Article X are solely for
the benefit of the Agent and the Banks, and the Company shall not have any
rights as a third party beneficiary of any of the provisions hereof.  In
performing its functions and duties under this Agreement, the Agent shall act
solely as agent of the Banks and does not assume and shall not be deemed to have
assumed any obligation towards or relationship of agency or trust with or for
the Company.

     10.2    Agent and Affiliates.  The Agent in its capacity as a Bank
hereunder shall have the same rights and powers hereunder as any other Bank and
may exercise or refrain from exercising the same as though it were not the
Agent.  The Agent and its Affiliates may (without having to account therefor to
any Bank) accept deposits from, lend money to, and generally engage in any kind
of banking, trust, financial advisory or other business with the Company or any
Subsidiary of the Company as if it were not acting as Agent hereunder, and may
accept fees and other consideration therefor without having to account for the
same to the Banks.

     10.3    Scope of Agent's Duties.  The Agent shall have no duties or
responsibilities except those expressly set forth herein, and shall not, by
reason of this Agreement, have a fiduciary relationship with any Bank, and no
implied covenants, responsibilities, duties, obligations or liabilities shall be
read into this Agreement or shall otherwise exist against the Agent.  As to any
matters not expressly provided for by this Agreement (including, without
limitation, collection and enforcement action under the Notes), the Agent shall
not be required to exercise any discretion or take any action, but may request
instructions from the Required Banks.  The Agent shall in all cases be fully
protected from liability to the Banks in acting, or in refraining from acting,
pursuant to the written instructions of the Required Banks or, when expressly
required by this Agreement, all the Banks, which instructions and any action or
omission pursuant thereto shall be binding upon all of the Banks; provided,
however, that the Agent shall not be required to act or omit to act if, in the
judgment of the Agent, such action or omission  may expose the Agent to personal
liability or is contrary to this Agreement, any Note, or applicable law.

     10.4    Reliance by Agent.  The Agent shall be entitled to rely upon any
certificate, notice, document or other communication (including any cable,
telegram, telex, facsimile transmission or oral communication) believed by it to
be genuine and correct and to have been sent or given by or on behalf of a
proper person.  The Agent may treat the payee of any Note as the holder thereof.
The Agent may employ agents (including, without limitation, collateral agents)
and may consult with legal counsel (who may be counsel for the Company),
independent public accountants and other experts selected by it and shall not be
liable to the Banks, except as to money or property received by it or its
authorized agents, for the negligence or misconduct of any such agent selected
by it with reasonable care or for any action taken or omitted to be taken by it
in good faith in accordance with the advice of such counsel, accountants or
experts.

     10.5    Default.  The Agent shall not be deemed to have knowledge of the
occurrence of any Default, unless the Agent has received written notice from a
Bank or the Company specifying such Default and stating that such notice is a
"Notice of Default".  In the event that the Agent receives such a notice, the
Agent shall give written notice thereof to the Banks.

<PAGE>   56


     10.6    Liability of Agent.  Neither the Agent nor any of its directors,
officers, agents, or employees shall be liable to the Banks for any action taken
or not taken by it or them in connection herewith with the consent or at the
request of the Required Banks or, when expressly required by this Agreement, all
the Banks or in the absence of its or their own gross negligence or willful
misconduct.  Neither the Agent nor any of its directors, officers, agents or
employees shall be responsible for or have any duty to ascertain, inquire into
or verify (a) any recital, statement, warranty or representation contained in
this Agreement or any Note, or in any certificate, report, financial statement
or other document furnished in connection with this Agreement, (b) the
performance or observance of any of the covenants or agreements of the Company,
(c) the satisfaction of any condition specified in Article VIII, except as to
the delivery to the Agent of documents that appear on their face to conform to
the requirements of Article VIII (other than requirements of any Bank under
Section 8.3(c) that are not known to the Agent), or (d) the validity,
effectiveness, legal enforceability, value or genuineness of this Agreement, the
Notes, or any  other instrument or document furnished in connection herewith.

     10.7    Nonreliance on Agent and Other Banks.  Each Bank acknowledges and
agrees that it has, independently and without reliance on the Agent or any other
Bank, and based on such documents and information as it has deemed appropriate,
made its own credit analysis of the Company and the Company's Subsidiaries and
its own decision to enter into this Agreement, and that it will, independently
and without reliance upon the Agent or any other Bank, and based on such
documents and information as it shall deem appropriate at the time, continue to
make its own analysis and decision in taking or not taking action under this
Agreement.  The Agent shall not be required to keep itself informed as to the
performance or observance by the Company of this Agreement, the Notes or any
other documents referred to or provided for herein or to inspect the properties
or books of the Company and, except for notices, reports and other documents and
information expressly required to be furnished to the Banks by the Agent
hereunder, the Agent shall not have any duty or responsibility to provide any
Bank with any information concerning the affairs, financial condition or
business of the Company or any of its Subsidiaries which may come into the
possession of the Agent or any of its Affiliates.

     10.8    Indemnification.  The Banks agree to indemnify the Agent (to the
extent not reimbursed by the Company, but without limiting any obligation of the
Company to make such reimbursement), ratably according to their respective
Commitment Percentages from and against any and all claims, damages, losses,
liabilities, costs or expenses of any kind or nature whatsoever (including,
without limitation, fees and disbursements of counsel) which may be imposed on,
incurred by, or asserted against the Agent in any way relating to or arising out
of this Agreement or the transactions contemplated hereby or any action taken or
omitted by the Agent under this Agreement; provided, however, that no Bank shall
be liable for any portion of such claims, damages, losses, liabilities, costs or
expenses resulting from the Agent's gross negligence or willful misconduct.
Without limitation of the foregoing, each Bank agrees to reimburse the Agent
promptly upon demand for its ratable share of any out-of-pocket expenses
(including, but not limited to, reasonable fees and expenses of counsel)
incurred by  the Agent in connection with the preparation, execution, delivery,
administration, modification, amendment or enforcement (whether through
negotiations, legal proceedings or otherwise) of, or legal advice in
respect of rights or responsibilities under, this Agreement, to the extent that
the Agent is not reimbursed for such expenses by the Company, but without
limiting the obligation of the Company to make such reimbursement; provided,
however, that no Bank shall be liable for any portion of such expenses incurred
as a result of the  Agent's gross negligence or willful misconduct.  Each Bank
agrees to reimburse the Agent promptly upon demand for its ratable share of any
amounts owing to the Agent by the Banks pursuant to this Section; provided that
no Bank shall be responsible for failure of any other Bank to make such share
available to the Agent.  If the indemnity furnished to the Agent under this
Section shall, in the reasonable judgment of the Agent, be insufficient or
become impaired, the Agent may call for additional indemnity from the Banks
(other than for the Agent's gross negligence or willful misconduct) and cease,
or not commence, to take any action until such additional indemnity is
furnished.

     10.9    Resignation of Agent.  The Agent may resign as such at any time
upon thirty days' prior written notice to the Company and the Banks.  In the
event of any such resignation, the Required Banks shall, by an instrument in
writing delivered to the Company and the Agent, appoint a successor, which shall
be (a) a Bank or (b) a commercial bank organized under the laws of the United
States or any State thereof and having a combined capital and surplus of at
least $500,000,000.  If a successor is not so appointed or does not accept such
appointment before the Agent'sEresignation becomes effective, the resigning
Agent may appoint a temporary successor to act until such appointment by the
Required Banks is made and accepted or if no such temporary successor is
appointed as provided above by the resigning Agent, the Required Banks shall
thereafter perform all the duties of the Agent hereunder until such appointment
by the Required Banks is made and accepted.  Any successor to the Agent shall
execute and deliver to the Company and the Banks an instrument accepting such
appointment and thereupon such successor Agent, without further act, deed,
conveyance or transfer shall become vested with all of the properties, rights,
interests, powers, authorities and obligations of its predecessor hereunder with
like effect as if originally named as Agent hereunder.  Upon request of such
successor Agent, the Company and the resigning Agent shall execute and deliver
such instruments of conveyance, assignment and further assurance and do such
other things as may reasonably be required for more fully and certainly vesting
and confirming in such successor Agent all such properties, rights, interests,
powers, authorities and obligations.  The provisions of this Article X shall
thereafter remain effective for such resigning Agent with respect to any
actions taken or omitted to be taken by such Agent while acting as the Agent
hereunder.

     10.10   Sharing of Payments.  The Banks agree among themselves that, in the
event that any Bank shall obtain payment in respect of any Loan or Letter of
Credit reimbursement obligation owing to such Bank under this Agreement through
the exercise of a right of set-off, banker's lien, counterclaim or otherwise in
excess of its ratable share as provided for in this Agreement, such Bank shall
promptly purchase from the other Banks participations in such Loans and other
obligations in such amounts, and make such other adjustments from time to time,
as shall be equitable to the end that all of the Banks share such payment in
accordance with their respective ratable shares as provided for in this
Agreement.  The Banks further agree among themselves that if payment to a Bank
obtained by such Bank through the exercise of a right of set-off, banker's lien,
counterclaim or otherwise as aforesaid shall be rescinded or must otherwise be
restored, each Bank which shall have shared the benefit of such payment shall,
by repurchase of participations theretofore sold, return its share of that
benefit to each Bank whose payment shall have been rescinded or otherwise
restored, together with interest thereon at the per annum rate, if any, at which
such Bank whose payment shall have been restored is liable with respect to such
restored payment.  The Company agrees that any Bank so purchasing such
a participation may, to the fullest extent permitted by law, exercise all
rights of payment, including set-off, banker's lien or counterclaim, with
respect to such participation as fully as if such Bank were a holder of such
Loan or other obligation in the amount of such participation. The Banks further
agree among themselves that, in the event that amounts received by the Banks
and the Agent hereunder are insufficient to pay all such obligations when due,
the fees and other amounts owing to the Agent in such capacity shall be paid
therefrom before payment of obligations owing to the Banks under this
Agreement.  Except as otherwise expressly provided in this Agreement, if any
Bank or the Agent shall fail to remit to the Agent or any other Bank an amount
payable by such Bank or the Agent to the Agent or such other Bank pursuant to
this Agreement on the date when such amount is due, such payments shall be made
together with interest thereon for each date from the date such amount is due
until the date such amount is paid to the Agent or such other Bank at a rate
per annum equal to the rate at which borrowings are available to the payee in
its overnight federal funds market.

     10.11   Withholding Tax Exemption.  Each Bank that is not organized and
incorporated under the laws of the United States or any State thereof agrees to
file with the Agent and the Company, in duplicate, (a) on or before the later of
(i) the Closing Date and (ii) the date such Bank becomes a Bank under this
Agreement and (b) thereafter, for each taxable year of such Bank (in the case of
a Form 4224) or for each third taxable year of such Bank (in the case of any
other form) during which interest or fees arising under this

Agreement and the Notes are received, unless not legally able to do so
as a result of a change in United States income tax law enacted, or treaty
promulgated, after the date specified in the preceding clause (a), on or prior
to the immediately following due date of any payment by the Company hereunder,
a properly completed and executed copy of either Internal Revenue Service Form
4224 or Internal Revenue Service Form 1001 and Internal Revenue Service Form
W-8 or Internal Revenue Service Form W-9 and any additional form necessary for
claiming complete exemption from United States withholding taxes (or such other
form as is required to claim complete exemption from United States withholding
taxes), if and as provided by the Code or other pronouncements of the United
States Internal Revenue Service, and such Bank warrants to the Company that the
form so filed will be true and complete; provided that such Bank's failure to
complete and execute such Form 4224 or Form 1001, or Form W-8 or Form W-9, as
the case may be, and any such additional form (or any successor form or forms)
shall not relieve the Company of any of its obligations under this Agreement,
except as otherwise provided in this Section 10.11

     10.12     The Co-Agents.  Each Co-Agent, in such capacity, shall have no
authority, duties, responsibilities, obligations, liabilities or functions under
this Agreement or the Notes.

                                  ARTICLE XI.

                                 MISCELLANEOUS

     11.1      Amendments, Etc.

          (a)      No amendment, modification, termination or waiver of any
provision of this Agreement nor any consent to any departure therefrom shall be
effective unless the same shall be in writing and signed by the Company (except
with respect to waivers by the Required Banks or all the Banks) and the Required
Banks and, to the extent any rights or duties of the Agent may be affected
thereby, the Agent, provided, however, that no such amendment, modification,
termination, waiver or consent shall, without the consent of the Agent and all
of the Banks, (i) subject to Section 3.10, authorize or permit the extension of
time for, or any reduction of the amount of, any payment of the principal of, or
interest (including the Applicable Margin) on, any Loan, or any fees or other
amount payable hereunder, or (ii) except as expressly authorized hereunder,

modify any other provision of this Agreement which by its terms requires the
consent of all the Banks.

          (b)      Any such amendment, waiver or consent shall be effective only
in the specific instance and for the specific purpose for which given.

          (c)      Notwithstanding anything herein to the contrary, no Bank that
is in default of any of its obligations, covenants or agreements under this
Agreement shall be entitled to vote (whether to consent or to withhold its
consent) with respect to any amendment, modification, termination or waiver of
any provision of this Agreement or any departure therefrom or any direction from
the Banks to the Agent, and, for purposes of determining the Required Banks at
any time when any Banks are in default under this Agreement, the Commitments and
Loans of such defaulting Banks shall be disregarded; provided that no action of
a type described in the proviso in Section 11.1(a) shall be binding on a
defaulting Bank without its written consent thereto.

all notices and other communications to or upon the parties hereto shall be
deemed to have been duly given or served if sent in writing (including
telecommunications) to the party to which such notice or other communication is
required or permitted to be given or served under this Agreement, to the address
or telex or telecopy number set forth below the name of such party on the
signature pages hereof, or at such other address or telex or telecopy number as
the parties hereto may hereafter specify to the others in writing. If for
purposes of receiving Invitations for Bid-Option Quotes and information
regarding Notices of Bid-Option Rate Borrowings, a Bank wishes to receive such
communications at an address or telex or telecopy number different from its
address or telex or telecopy number for other purposes under this Agreement, the
Agent shall communicate with such Bank for such purposes at such
different address, telex or telecopy number following the Agent's receipt of a
written notice from such Bank requesting that the Agent do so.  All mailed
notices or other communications shall be by registered or certified mail,
postage prepaid, with return receipt requested. All notices or other
communications sent by means of telecopy, telex or other wire transmission
shall be made with request for assurance of receipt in a manner typical with
respect to communications of that type.  Written notices or other
communications shall be deemed delivered upon receipt if delivered by hand, 3
Business Days after mailing if mailed, or 1 Business Day after deposit with an
overnight courier service if delivered by overnight courier.  Notices or other
communications provided by any of the other means referred to above shall be
deemed delivered upon receipt.  Notwithstanding the foregoing, all notices to
the Agent shall be effective only when actually received by the Agent, and all
notices from the Agent to any Bank regarding such Bank's obligation to fund
Loans or to make payment under Section 3.3(d) shall be effective only when
actually received by such Bank.

          (b)      Notices by the Company to the Agent with respect to
terminations or reductions of the Commitments pursuant to SectionE3.8, requests
for Loans and Letter of Credit Issuances pursuant to SectionE3.2, 3.3 or 3.4,

given by telephone shall be deemed effective upon receipt thereof by the party
to whom such notice is to be given.

     11.3      No Waiver By Conduct; Remedies Cumulative.  No course of dealing
on the part of the Agent or any Bank, nor any delay or failure on the part of
the Agent or any Bank in exercising any right, power or privilege hereunder or
under any Note shall operate as a waiver of such right, power or privilege or
otherwise prejudice the Agent's or such Bank's rights and remedies hereunder;
nor shall any single or partial exercise thereof preclude any further exercise
thereof or the exercise of any other right, power or privilege.  No right or
remedy conferred upon or reserved to the Agent or any Bank under this Agreement,
or any Note, is intended to be exclusive of any other right or remedy, and every
right and remedy shall be cumulative and in addition to every other right or
remedy granted hereunder or thereunder or now or hereafter existing under any
applicable law.  Every right and remedy granted by this Agreement or by
applicable law to the Agent or any Bank may be exercised from time to time and
as often as may be deemed expedient by the Agent or any Bank and, unless
contrary to the express provisions of this Agreement, or the Notes, irrespective
of the occurrence or continuance of any Default.

     11.4      Reliance on and Survival of Various Provisions.  All terms,
covenants, agreements, including, without limitation, under Sections 5.3, 5.5
and 11.5, representations and warranties of the Company made herein or in any
certificate, report, financial statement or other document furnished by or on
behalf of the Company pursuant to this Agreement shall be deemed to be material
and to have been relied upon by the Banks, notwithstanding any investigation
heretofore or hereafter made by any Bank or on such Bank's behalf, and shall
survive the repayment in full of the Loans and the termination of the
Commitments.

connection with the preparation of this Agreement, any waiver or consent
hereunder or any amendment hereof or any Default, (ii) all reasonable costs and
expenses of the Agent or such Bank, including reasonable fees and disbursements

order, injunction or other process or decree restraining or seeking to restrain

Letter of Credit and any and all costs and expenses which it may incur relative
to any payment under any Letter of Credit, provided, that the Company shall not
be liable under this clause (ii) to the extent, but only to the extent, any such
costs and expenses of the Agent or any Bank are caused by the Agent's or such
Bank's breach of this Agreement or gross negligence, and (iii) if an Event of
Default occurs, all reasonable expenses incurred by the Agent or such Bank,
including reasonable fees and disbursements of counsel (including in-house
counsel), in connection with such Event of Default and collection and other
enforcement proceedings resulting therefrom.  The Company shall indemnify each
Bank against any transfer taxes, documentary taxes, assessments or charges made
by any governmental authority by reason of the execution and delivery of this
Agreement or the Notes.

          (b)      The Company shall indemnify each Bank and the Agent, and
their respective officers, directors, employees and agents, and hold each Bank
and the Agent, and their respective officers, directors, employees and agents,
harmless from and against any and all liabilities, losses, damages, costs and
expenses of any kind (including, without limitation, the reasonable fees and
disbursements of counsel for any Bank or the Agent or any such Person in
connection with any investigative, administrative or judicial proceeding,
whether or not such Bank, the Agent or any such Person, as the case may be,
shall be designated a party thereto) which may be incurred by any Bank, by the
Agent or by any such Person, substantially relating to or arising out of any
actual or proposed use of proceeds of Loans or Letters of Credit for the purpose
of acquiring assets or capital stock of any other Person; provided that none of
the Agent, any Bank or any such Person shall have the right to be indemnified
hereunder for its own gross negligence or willful misconduct as determined by a
court of competent jurisdiction.

          (c)      The Company hereby further indemnifies and agrees to hold the
Banks and the Agent, and their respective officers, directors, employees and
agents harmless from and against any and all claims, damages, losses,
liabilities, costs and expenses of any kind or nature whatsoever which the Banks
or the Agent or any such Person may incur or which may be claimed against any of
them by reason of or in connection with any Letter of Credit, and neither any
Bank nor the Agent or any of their respective officers, directors, employees or
agents shall be liable or responsible for:  (i) the use which may be made of any
Letter of Credit or for any acts or omissions of any beneficiary in connection
therewith; (ii) the validity, sufficiency or genuineness of documents or of any
endorsements thereon, even if such documents should in fact prove to be in any
or all respects invalid, insufficient, fraudulent or forged; (iii) payment by
the Agent to the beneficiary under any Letter of Credit against presentation of
documents which do not comply with the terms of any Letter of Credit, including
failure of any documents to bear any reference or adequate reference to such
Letter of Credit;  (iv) any error, omission, interruption or delay in
transmission, dispatch or delivery of any message or advice, however
transmitted, in connection with any Letter of Credit; or (v) any other event or
circumstance whatsoever arising in connection with any Letter of Credit;
provided, however, that the Company shall not be liable hereunder to the Banks
and the Agent and such other Persons and the Agent shall be liable to the
Company to the extent, but only to the extent, of any direct, as opposed to
consequential or incidental, damages suffered by the Company which were caused
by (A) the Agent'sEwrongful dishonor of any Letter of Credit after the
presentation to it by the beneficiary thereunder of a draft or other demand for
payment and other documentation strictly complying with the terms and
conditions of such Letter of Credit, or 



                      MASCOTECH, INC. CREDIT AGREEMENT

(B) the Agent's payment under any Letter of Credit to the extent, but
only to the extent, that such payment constitutes gross negligence or willful
misconduct of the Agent.  The inclusion of any event in clauses (i) - (vii) of
Section 3.3(f) shall not by itself preclude a finding that such event
constitutes gross negligence or willful misconduct of the Agent.  It is
understood that in making any payment under a Letter of Credit the Agent will
rely on documents presented to it under such Letter of Credit as to any and all
matters set forth therein without further investigation and regardless of any
notice or information to the contrary, and such reliance and payment against
documents presented under a Letter of Credit substantially complying with the
terms thereof shall not be deemed gross negligence or willful misconduct of the
Agent in connection with the payment.

     11.6      Successors and Assigns.

          (a) This Agreement shall be binding upon and inure to the benefit of
the parties hereto and their respective successors and assigns, provided that
the Company may not, without the prior written consent of all the Banks, assign
its rights or obligations hereunder or under the Notes, and the Banks shall not
be obligated to make any Loan hereunder to any Person other than the Company,
and the Agent shall not be obligated to issue any Letter of Credit for the
account of any Person other than the Company or any Consolidated Subsidiary of
the Company.

          (b) The Agent from time to time in its sole discretion may appoint
agents for the purpose of servicing and administering this Agreement and the
transactions contemplated hereby and enforcing or exercising any rights or
remedies of the Agent provided under this Agreement, the Notes or otherwise. In
furtherance of such agency, the Agent may from time to time direct that the
Company provide notices, reports and other documents contemplated by this
Agreement (or duplicates thereof) to such agent.  The Company hereby consents to
the appointment of such agent and agrees to provide all such notices, reports
and other documents and to otherwise deal with such agent acting on behalf of
the Agent in the same manner as would be required if dealing with the Agent
itself.

          (c) Any Bank may sell a participation interest to any financial
institution(s), and such financial institution(s) may further sell a
participation interest (undivided or divided) to any financial institution(s),
in its Commitment and the Loans and risk of the Letters of Credit and such
Bank's or such participating financial institution's, as the case may be, rights
and benefits under this Agreement and the Notes, and to the extent of that
participation, such participant or participants shall have the same rights and
benefits against the Company under Section 9.3 as it or they would have had if
such participant or participants were the Bank making the Loans to the Company
hereunder, provided, however, that in purchasing such participation interest(s)
each such participant shall be deemed to have agreed to share with the Banks the
proceeds thereof as provided in Section 10.10 as fully as if such participant
were a Bank hereunder; and provided further, however, that (i) the obligations
under this Agreement of each Bank selling a participation interest hereunder
shall remain unmodified and fully effective and enforceable against such Bank,
(ii) such Bank shall remain solely responsible to the other parties
hereto for the performance of such obligations, (iii) such Bank shall remain
the holder of its Notes for all purposes of this Agreement, (iv) the Company,
the Agent and the other Banks shall continue to deal solely and directly with

under this Agreement other than action requiring the consent of all of the
Banks hereunder.  Each Bank shall give the Company prior written notice of each
sale by such Bank of a participation interest under this Section 11.6(c).  Each
participant shall be entitled to the benefits of Sections 5.3 and 5.5 with
respect to its participation interest as if it were a Bank; provided that no
participant shall be entitled to receive any greater amount pursuant to such
Sections 5.3 and 5.5 than the Bank that originally sold such participation
interest would have been entitled to receive in respect of such participation
interest had no such sale taken place.

          (d)      Any Bank may, with the prior written consent of the Company
and the Agent (which consent in each case will not unreasonably be withheld, and
which consent in the case of the Company may not be withheld if there is any
Event of Default under Section 9.1(a), (f) or (g)) assign to one or more banks
or other financial institutions all or a portion of its rights and obligations
under this Agreement (including, without limitation, all or a portion of its
Commitment, the Syndicated Loans owing to it, its share of the risk of Letters
of Credit, and the Syndicated Notes held by it); provided, however, that (i)
each such assignment shall be of a uniform, and not a varying, percentage of all
rights and obligations (other than any Bid-Option Loan or Bid-Option Note), (ii)
the amount of the Commitment of any assignee Bank as of any date, after giving
effect to each assignment to such assignee that is effective on such date, shall
in no event be less than $10,000,000, (iii) except in the case of an assignment
of all of a Bank's rights and obligations under this Agreement, (A) the amount
of the Commitment of the assigning Bank being assigned pursuant to each such
assignment (determined as of the date of the Assignment and Acceptance with
respect to each such assignment) shall in no event be less than $5,000,000 or an
integral multiple of $5,000,000, or such lesser amount as the Company and the
Agent may consent to and (B) after giving effect to each such assignment, the
amount of the Commitment of the assigning Bank shall in no event be less than
$10,000,000, (iv) the parties to each such assignment shall execute and deliver
to the Agent, for its acceptance and recording in the Register (as hereinafter
defined), an Assignment and Acceptance in the form of ExhibitEK hereto (an
"Assignment and Acceptance"), together with the Notes subject to such assignment
and a processing and recordation fee of $3,000, and (v) any Bank may without the
consent of the Company or the Agent, and without paying any fee, assign to any
Affiliate of such Bank that is a bank or financial institution all of its rights
and obligations under this Agreement.  Upon such execution, delivery, acceptance
and recording, from and after the effective date specified in such Assignment
and Acceptance, (i) the assignee thereunder shall be a party hereto and, to the
extent that rights and obligations hereunder have been assigned to it pursuant
to such Assignment and Acceptance, have the rights and obligations of a Bank
hereunder and (ii) the Bank assignor thereunder shall, to the extent that rights
and obligations hereunder have been assigned by it pursuant to such Assignment
and Acceptance, relinquish its rights and be released from its obligations under
this Agreement (and, in the case of an Assignment and Acceptance covering all of
the remaining portion of an assigning Bank's rights and obligations under this
Agreement, such Bank shall cease to be a party hereto).

          (e)      By executing and delivering an Assignment and Acceptance, (i)
the Bank assignor thereunder and the assignee thereunder confirm to and agree
with each other and the other parties hereto as follows: (A) other than as
provided in such Assignment and Acceptance, such assigning Bank makes no
representation or warranty and assumes no responsibility with respect to any
statements, warranties or representations made in or in connection with this
Agreement or any instrument or other document furnished pursuant hereto or the
execution, legality, validity, enforceability, genuineness, sufficiency or value
of this Agreement or any instrument or other document furnished pursuant hereto;
and (B) such assigning Bank makes no representation or warranty and assumes no
responsibility with respect to the financial condition of the Company or the
performance or observance by the Company of any of its obligations under this
Agreement or any instrument or other document furnished pursuant hereto, and
(ii) the assignee thereunder confirms to the assignor thereunder and the other
parties hereto as follows: (A) such assignee confirms that it has received a
copy of this Agreement, together with copies of the financial statements
referred to in Section 6.6 and such other documents and information as it has
deemed appropriate to make its own credit analysis and decision to enter into
such Assignment and Acceptance; (B) such assignee will, independently and
without reliance upon the Agent, such assigning Bank or any other Bank and based
on such documents and information as it shall deem appropriate at the time,
continue to make its own credit decisions in taking or not taking action under
this Agreement; (C) such assignee appoints and authorizes the Agent to take such
action as agent on its behalf and to exercise such powers and discretion under
this Agreement as are delegated to the Agent by the terms hereof, together with
such powers and discretion as are reasonably incidental thereto; and (D) such
assignee agrees that it will perform in accordance with their terms all of the
obligations that by the terms of this Agreement are required to be performed by
it as a Bank and agrees that shall be bound by all the terms and provisions of
this Agreement.

          (f)      The Agent shall maintain a copy of each Assignment and
Acceptance delivered to and accepted by it and a register for the recordation of
the names and addresses of the Banks and the Commitment of, and principal amount
of the Loans owing to, each Bank from time to time (the "Register").  The
entries in the Register shall be conclusive and binding for all purposes, absent
demonstrable error, and the Company, the Agent and the Banks may treat each
Person whose name is recorded in the Register as a Bank hereunder for all
purposes of this Agreement.  The Register shall be available for inspection by
the Company or any Bank at any reasonable time and from time to time upon
reasonable prior notice.

          (g)      Upon its receipt of an Assignment and Acceptance executed by
an assigning Bank and an assignee and, unless such assignment is of only a
portion of such assigning Bank's rights and obligations hereunder, the Notes
subject to such assignment, the Agent shall, if such Assignment and Acceptance
has been completed and the Agent and the Company have given their written
consent under Section 11.6(d) (if required), (i) accept such Assignment and
Acceptance, (ii) record the information contained therein in the Register and
(iii) give prompt notice thereof to the Company.  Within five Business Days
after its receipt of such notice, the Company, at its own expense, shall execute
and deliver to the Agent (in exchange for the surrendered Notes unless such
assignment is of only a portion of such assigning Bank's rights and obligations
hereunder) a new Syndicated Note to the order of such assignee and a new
Bid-Option Note to the order of such assignee.  Such new Syndicated Note and
Bid-Option Note shall be dated the effective date of such Assignment and
Acceptance and shall otherwise be in substantially the form of Exhibits A and B
hereto, respectively.

          (h)      If any Reference Bank makes an assignment of all of its
Commitment and Syndicated Loans to an unaffiliated institution pursuant to
subsection (d) above, or if the Fixed Rate Loans of any Reference Bank are
repaid pursuant to Section 5.2 or 5.3, the Agent shall, with the consent of the
Required Banks and the Company, appoint another Bank to act as
Reference Bank hereunder. No assignee of any Bank shall be entitled to receive
any greater payment under SectionE5.3 than such Bank would have been entitled
to receive with respect to the rights assigned or otherwise transferred, unless
such assignment is made by reason of the provisions of Section 5.2 or 5.3
requiring such Bank to designate a different lending office under certain
circumstances or at a time when the circumstances giving rise to such greater
payment did not exist.

          (i)      Each Bank may assign to one or more banks or other financial
institutions any Bid-Option Note held by it.  Any such Bank assigning a
Bid-Option Note shall for all purposes of this Agreement be deemed to be the
holder of such Note, and no assignee under this Section 11.6(i) shall as a
result of such assignment become a "Bank" under this Agreement.

          (j)      Notwithstanding any other provision set forth in this
Agreement, any Bank may at any time create a security interest in, or assign,
all or any portion of its rights under this Agreement (including, without
limitation, the Loans owing to it and the Note or Notes held by it) in favor of
any Federal Reserve Bank in accordance with Regulation A of the Board of
Governors of the Federal Reserve System; provided that such creation of a
security interest or assignment shall not release such Bank from its obligations
under this Agreement.

          11.7  Confidentiality.  Each Bank agrees that all documentation and
other information made available by the Company to such Bank under the terms of
this Agreement shall (except (a) to the extent required by legal or governmental
process or otherwise by law, or (b) if such documentation and other information
is publicly available or hereafter becomes publicly available other than by
action of such Bank, or was theretofore known to such Bank independent of any
disclosure thereto by the Company, or (c) to the extent of necessary disclosure
to such Bank's accountants, attorneys or regulators, or (d) in any litigation or
similar proceedings related to this Agreement, the Notes or any Letter of
Credit) be held in the strictest

confidence by such Bank and disclosed only to those officers, employees
and agents of such Bank or of any Affiliate of such Bank involved in the
administration of the credit from time to time outstanding from such Bank to
the Company or otherwise involved in servicing, maintaining or further
developing the relationship between such Bank and the Company, each of which
officers, employees and agents shall, except as permitted under this Section
11.7 generally with respect to such Bank, hold such documentation and other
information in the strictest confidence and to be used only in connection with
this Agreement; provided that (i) such Bank may disclose such documentation and
other information, and all other information that has been delivered to such
Bank by or on behalf of the Company prior to the Closing Date in connection
with such Bank's credit evaluation of the Company and its Subsidiaries, to any
other financial institution to which such Bank sells or proposes to sell a
participation or other interest in any of its Loans hereunder (or under any
other credit agreement with the Company), if such other financial institution,
prior to such disclosure, agrees for the benefit of the Company to comply with
the provisions of this Section 11.7 (including the provisions of this Section
11.7 allowing further disclosure to other financial institutions to whom a sale
of a participation or other interest is proposed), or to any Federal Reserve
Bank and (ii) such Bank may disclose the provisions of this Agreement and the
Notes and the amounts, maturities and interest rates of its Loans and the
amounts of Letters of Credit (and similar information relating to any other
credit agreement with the Company) to any purchaser or potential purchaser of
any interest of such Bank in any Loan to the Company.

     11.8    Counterparts; Effectiveness of Telecopied Signatures.  This
Agreement may be executed in any number of counterparts, all of which taken
together shall constitute one and the same instrument and any of the parties
hereto may execute this Agreement by signing any such counterpart.  Delivery of
a telecopied signature on this Agreement shall be as effective against the
signer as delivery of its original signature.

     11.9    Table of Contents and Headings.  The table of contents and the
headings of the various subdivisions hereof are for the convenience of reference
only and shall in no way modify any of the terms or provisions hereof.

     11.10   Construction of Certain Provisions.  If any provision of this
Agreement refers to any action to be taken by any Person, or which such Person
is prohibited from taking, such provision shall be applicable whether such
action is taken directly or indirectly by such Person, whether or not expressly
specified in such provision.

     11.11   Independence of Covenants.  All covenants hereunder shall be given
independent effect so that if a particular action or condition is not permitted
by any such covenant, the fact that it would be permitted by an exception to, or
would be otherwise within the limitations of, another covenant shall not avoid
the occurrence of a Default or any event or condition which with notice or lapse
of time, or both, could become such a Default if such action is taken or such
condition exists.

     11.12   Interest Rate Limitation.  Notwithstanding any provisions of this
Agreement or the Notes, in no event shall the amount of interest paid or agreed
to be paid by the Company exceed an amount computed at the highest rate of
interest permissible under applicable law.  If, from any circumstances
whatsoever, fulfillment of any provision of this Agreement or the Notes at the
time performance of such provision shall be due, shall involve exceeding the
interest rate limitation validly prescribed by law which a court of competent
jurisdiction may deem applicable hereto, then, ipso facto, the obligations to be
fulfilled shall be reduced to an amount computed at the highest rate of interest
permissible under applicable law, and if for any reason whatsoever any Bank
shall ever receive as interest an amount which would be deemed unlawful under
such applicable law such interest shall be automatically applied to the payment
of principal of the Loans outstanding hereunder (whether or not then due and
payable) and not to the payment of interest, or shall be refunded to the Company
if such principal and all other obligations of the Company to the Banks have
been paid in full.

     11.13   Substitution of Banks.

          (a)      Upon five Business Days' written notice in the form of
Exhibit L delivered to the Agent and the applicable Bank, the Company may
replace any one or more of the Banks.  Upon the date of its effectiveness, such
notice shall terminate the Commitment of such Bank entirely, provided that the
Company shall prepay each Loan of such Bank (if any) in full on the effective
date of such termination, together with accrued interest thereon, all amounts
due pursuant to Sections 5.3 and 5.5, all accrued facility fees with respect to
such Bank and all other amounts owing to such Bank hereunder to such effective
date.

          (b)      If the Company shall terminate the Commitment of any Bank
pursuant to the provisions of subsection (a) of this Section 11.13, the Company
shall designate another bank or other banks (which may be one of the Banks) (in
either case, an "Additional Bank") to be parties to this Agreement,
provided, that (i) without the consent of the Agent, the total number of
Additional Banks (other than those that were already Banks) may not exceed the
total number of Banks whose Commitments are terminated pursuant to Section
11.13(a) plus three, (ii) the amount of the Commitment of any Additional Bank
may not be less than $10,000,000, (iii) the amount of the Commitment(s) of the
Additional Bank(s) (or, if any such Additional Bank already is a Bank, the added
portion of such Bank's Commitment) shall in the aggregate equal the amount of
the Commitment so terminated and (iv) the Company or the Additional Bank, and
not the Bank being terminated pursuant to subsection (a) of this Section 11.13,
shall pay the processing and recordation fee required under Section 11.6(d)(iv).
Any Additional Bank shall become a party to this Agreement and be considered a
Bank hereunder for all purposes if (i) it shall agree in writing to be bound by
all of the terms and provisions of this Agreement, such agreement to specify the
amount of the Commitment of such Additional Bank and to be otherwise in form and
substance satisfactory to the Agent, (ii) it shall make Syndicated Loans to the
Company in principal amounts which bear the same ratio to the amounts of the
Syndicated Loans of other Banks (including other Additional Banks) then
outstanding or to be concurrently outstanding as the amount of the Commitment of
such Additional Bank bears to the then aggregate amount of the Commitments of
such other Banks (including other Additional Banks), and (iii) a copy of such
agreement and of evidence satisfactory to the Agent of the making of such Loans
shall be furnished to the Agent.

     11.14   Collateral.  Each of the Banks represents to the Agent and each of
the other Banks that it, in good faith, is not relying upon any "margin
stock"(as defined in Regulation U) as collateral in the extension or maintenance
of the credit provided for in this Agreement.

     11.15   Governing Law.  This Agreement is a contract made under, and shall
be governed by and construed in accordance with, the law of the State of
Michigan applicable to contracts made and to be performed entirely within such
State and without giving effect to choice of law principles of such State.

     11.16   Integration and Severability.  This Agreement and the Notes embody
the entire agreement and understanding among the Company, the Agent, and the
Banks, and supersede all prior agreements and understandings, relating to the
subject matter hereof and thereof.  In case any one or more of the obligations
of the Company under this Agreement or any Note shall be invalid, illegal or
unenforceable in any jurisdiction, the validity, legality and enforceability of
the remaining obligations of the Company shall not in any way be affected or
impaired thereby, and such invalidity, illegality or unenforceability in one
jurisdiction shall not affect the validity, legality or enforceability of the
obligations of the Company under this Agreement or any Note in any other
jurisdiction.

     11.17   WAIVER OF JURY TRIAL.  THE BANKS, THE AGENT, THE CO-AGENTS AND THE
COMPANY, AFTER CONSULTING OR HAVING HAD THE OPPORTUNITY TO CONSULT WITH COUNSEL,
KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE ANY RIGHT ANY OF THEM

NBD Bank, as Agent
611 Woodward Avenue

Attention:  Richard Huttenlocher

Ladies and Gentlemen:

     Reference is made to the Credit Agreement, dated as of February 28, 1997
(the "Credit Agreement"), by and among MASCOTECH, INC., a Delaware corporation,
the banks (the "Banks") and the co-agents (the "Co-Agents") party thereto, and
NBD Bank, as agent (in such capacity, the "Agent") for the Banks.  I am Vice
President and Corporate Counsel for the Company, and in the capacity of counsel
for the Company I have been requested by the Company to give my opinion pursuant
to Section 8.3(a) of the Credit Agreement.  For purposes of this opinion, the
terms used in this opinion which are not defined herein shall have the
respective meanings set forth in the Credit Agreement.

     I have examined the Credit Agreement and the Notes, the Convertible
Subordinated Debentures referred to in the definition of the term "Subordinated
Debt" in the Credit Agreement and the indenture governing the issuance of such
Convertible Subordinated Debentures (the "Subordinated Debt Documents"), and
certified copies of the Company's certificate of incorporation, by-laws and
board of directors' resolutions authorizing the Company's participation in the
transactions contemplated by the Credit Agreement.  I have also examined copies
of all such documents and records of the Company and all such other documents
and records, and have made such investigations of law, as I have deemed
necessary and relevant as a basis for my opinion.

     Based upon the foregoing, it is my opinion that:

     (a) The Company is a corporation duly organized and validly existing in
good standing under the laws of the State of Delaware and is duly authorized to
do business and is in good standing in the State of Michigan.

     (b) The Company has all requisite corporate power and authority to conduct
its business substantially as now being conducted and to own its properties.

     (c) The Company has full power, authority and legal right to execute and
deliver 


<PAGE>   98
To the Banks, Co-Agents and Agent
February __, 1997
Page 2


the Credit Agreement and the Notes, to perform and observe the terms and
provisions thereof, and to borrow thereunder.  The execution, delivery and
performance by the Company of its obligations under the Credit Agreement and the
Notes and the borrowings thereunder have been duly authorized by the proper
corporate proceedings and do not contravene any provision of applicable law or
regulation or of the certificate of incorporation or by-laws of the Company or
any Subsidiary, or any order of any court, regulatory body or arbitral tribunal
or any judgment, order or decree, or, to my knowledge after due inquiry, any
agreement or instrument, binding on the Company or any Subsidiary, or, to my
knowledge after due inquiry, result in the creation of any lien, charge or
encumbrance upon any of their respective property or assets pursuant to any
agreement or instrument to which any of them is a party or binding upon any of
them.

     (d) The Credit Agreement and the Notes constitute legal, valid and binding
obligations of the Company enforceable against the Company in accordance with
their respective terms.

     (e) There are, to my knowledge after due inquiry, no suits, proceedings or
actions at law or in equity or by or before any governmental commission, board,
bureau, or other administrative agency pending or threatened against or
affecting the Company or any Subsidiary, (i) in which there is a reasonable
possibility of an adverse decision which is likely to materially and adversely
affect the financial condition or business of the Company and its Subsidiaries,
taken as a whole, or (ii) which will in any manner affect the enforceability or
validity of the Credit Agreement or any Note.

     (f) No approval, consent or authorization of or filing or registration with
any state or federal agency or regulatory authority is necessary for the
execution or delivery by the Company of the Credit Agreement or the issuance of
the Notes, for the validity or enforceability of the Credit Agreement or the
Notes, or for the performance by the Company of any of the terms or conditions
thereof or for any borrowing by the Company thereunder.

     (g) The Notes represent Senior Indebtedness as that term is defined in the
Subordinated Debt Documents.

     The opinion expressed in paragraph (d) above is subject to the
qualifications that the enforcement of the rights and remedies set forth in the
Credit Agreement and the Notes is subject to the effect of applicable
bankruptcy, insolvency and other similar laws affecting the enforcement of
creditors' rights generally, and to general principles of equity, whether
applied in a proceeding at law or in equity.

things, for the extension to the Company of a bank credit in the principal sum
of the Dollar Equivalent of $575,000,0000.  Capitalized terms not otherwise
defined herein are used with the respective meanings ascribed thereto in the
Credit Agreement.

     In connection with this opinion we have examined: (a) a copy of the
Certificate of Incorporation of the Company certified to _______ __, 1997 by
the Secretary of State of Delaware and to ________ __, 1997 by an officer of
the Company, (b) a copy of the Bylaws of the Company certified to _______ __,
1997 by an officer of the Company, (c) copies of Certificates of Good Standing
of the Company under the laws of the States of Delaware and Michigan dated,
respectively, _________ __, 1997 and _____________ __, 1997, (d) a copy of
resolutions of the Board of Directors of the Company authorizing the execution,
delivery and performance of the Credit Agreement and the Notes, certified as
true and correct by an officer of the Company, (e) a certificate of incumbency
and specimen signatures of authorized officers of the Company, in the form
being delivered to the Agent pursuant to Section 8.3(d) of the Credit

being delivered to the Agent pursuant to Section 8.3(e) of the Credit
Agreement, (g) a certificate of the chief ____ officer of the Company, in the
form being delivered to the Agent pursuant to Section 8.3(g) of the Credit
Agreement, and (h) the Credit Agreement and the Notes.  We have also examined
the opinion of Mr. David B. Liner, Vice President and Corporate Counsel of the
Company, dated February __, 1997, addressed to you and delivered to the Agent
pursuant to Section 8.3(a) of the Credit Agreement.  We have made no
independent investigation of any of the foregoing matters 

<PAGE>   101

or of any other matters.

     Based solely on such information, it is our opinion that: (a) the

responsive to the requirements of the Credit Agreement; and (b) while we have
not independently considered the matters covered by the opinion of Mr. Liner
furnished pursuant to Section 8.3(a) of the Credit Agreement to the extent
necessary to enable us to express the conclusions stated therein, such opinion
is in substantially acceptable legal form and is substantially responsive to
the requirements of the Credit Agreement.

          4. Suspension of Payment When Senior Indebtedness in Default.

               (a) Unless Section 3 shall be applicable, upon (1) the occurrence
of a Payment Default and (2) receipt by the Trustee of written notice of such
occurrence, then no payment or distribution of any assets of the Company of any
kind or character shall be made by the Company on account of the Subordinated
Indebtedness or on account of the purchase or redemption or other acquisition of
any Subordinated Indebtedness unless and until such Payment Default shall have
been cured or waived in writing or shall have ceased to exist or such Senior
Indebtedness shall have been discharged or paid in full in cash or Cash
Equivalents, after which the Company shall resume making any and all required
payments in respect of the Subordinated Indebtedness, including any missed
payments.

               (b) Unless Section 3 shall be applicable, upon (1) the occurrence
of a Non-Payment Default and (2) receipt by the Company or the Trustee from the
representative of holders of such Designated Senior Indebtedness of written
notice of such occurrence, then no payment or distribution of any assets of the
Company of any kind or character shall be made by the Company on account of any
Subordinated Indebtedness or on account of the purchase or redemption or other
acquisition of any Subordinated Indebtedness for a period ("Payment Blockage
Period") commencing on the earlier of the date of receipt by the Company or the
date of receipt by the Trustee of such notice from such representative unless
and until (subject to any blockage of payments that may then be in effect under
paragraph (a) of this Section) (x) more than 179 days shall have elapsed since
receipt of such written notice by the Company or the Trustee, whichever was
earlier, (y) such Non-Payment Default shall have been cured or waived in writing
or shall have ceased to exist or such Designated Senior Indebtedness shall have
been discharged or (z) such Payment Blockage Period shall have been terminated
by written notice to the Company or the Trustee from such representative
initiating such Payment Blockage Period, after which, in the case of clause (x),
(y) or (z), the Company shall resume making any and all required payments in
respect of any Subordinated Indebtedness, including any missed payments.
Notwithstanding any other provision of this Agreement, only one Payment Blockage
Period may be commenced within any consecutive 360-day period, and no event of
default with respect to Designated Senior Indebtedness which existed or was
continuing on the date of the commencement of any Payment Blockage Period
initiated by or on behalf of such Designated Senior Indebtedness shall be, or be
made, the basis for the commencement of a second Payment Blockage Period whether
or not within a period of 360 consecutive days unless such event of default
shall have been cured or waived for a period of not less than 90 consecutive
days subsequent to the commencement of such initial Payment Blockage Period (it
being acknowledged that any subsequent action, or any breach of any financial
covenant for a period commencing after the date of commencement of such Payment
Blockage Period, that, in either case, would give rise to a Non-Payment 


                                      -8-
<PAGE>   110

Default pursuant to any provision under which a Non-Payment Default previously
existed or was continuing shall constitute a new Non-Payment Default for this
purpose; provided that, in the case of a breach of a particular financial
covenant, the Company shall have been in compliance for at least one full period
of not less than 90 consecutive days commencing after the date of commencement
of such Payment Blockage Period).  In no event will a Payment Blockage Period
extend beyond 179 days from the date of the receipt by the Trustee of the notice
and there must be a 181-consecutive day period in any 360-day period during
which no Payment Blockage Period is in effect.

               (c) In the event that, notwithstanding the foregoing, the Company
shall make any payment to the Trustee or the holder of any Subordinated
Indebtedness prohibited by the foregoing provisions of this Section, then and in
such event such payment shall be received and held in trust for the benefit of
the holders of Senior Indebtedness and paid over and delivered forthwith to the
Company.


          5. Payment Permitted If No Default.

          Nothing contained herein or in any instrument evidencing the
Subordinated Indebtedness shall prevent the Company, at any time except during
the pendency of any case, proceeding, dissolution, liquidation or other winding
up, assignment for the benefit of creditors or other marshalling of assets and
liabilities of the Company referred to in Section 3 or under the conditions
described in Section 4, from making payments at any time of principal of (and
premium, if any, on) or interest on the Subordinated Indebtedness.


          6. Subrogation to Rights of Holders of Senior Indebtedness.

          Subject to the payment in full in cash or Cash Equivalents of all
Senior Indebtedness, the holders of the Subordinated Indebtedness shall be
subrogated to the rights of the holders of such Senior Indebtedness to receive
payments and distributions of cash, property and securities applicable to the
Senior Indebtedness until the principal of (and premium, if any, on) and
interest on the Subordinated Indebtedness shall be paid in full.  For purposes
of such subrogation, no payments or distributions to the holders of Senior
Indebtedness of any cash, property or securities to which the holders of the
Subordinated Indebtedness or the Trustee would be entitled except for the
provisions in this Article, shall, as among the Company, its creditors other
than holders of Senior Indebtedness, and the holders of the Subordinated
Indebtedness, be deemed to be a payment or distribution by the Company to or on
account of the Senior Indebtedness.


          7. Provisions Solely to Define Relative Rights.


                                      -9-
<PAGE>   111


          The provisions of this Article are and are intended solely for the
purpose of defining the relative rights of the holders of the Subordinated
Indebtedness on the one hand and the holders of Senior Indebtedness on the other
hand. Nothing contained in this Article or elsewhere in the Subordinated
Indenture or in any Securities is intended to or shall (a) impair, as between
the Company and the holders of the Subordinated Indebtedness, the obligation of
the Company, which is absolute and unconditional, to pay to the holders of the
Securities the principal of (and premium, if any, on) and interest on the
Securities as and when the same shall become due and payable in accordance with
their terms; or (b) affect the relative rights against the Company of the
holders of the Securities and creditors of the Company other than the holders of
Senior Indebtedness; or (c) prevent the Trustee or the holder of any Security
from exercising all remedies otherwise permitted by applicable law upon default
under the Subordinated Indenture, subject to the rights, if any, under this
Article of the holders of Senior Indebtedness.


          8. Trustee to Effectuate Subordination.

          Each holder of any Security by its acceptance thereof authorizes and
directs the Trustee on its behalf to take such action as may be necessary or
appropriate to effectuate the subordination provided in this Article and
appoints the Trustee its attorney-in-fact for any and all such purposes.


          9. No Waiver of Subordination Provisions.

               (a) No right of any present or future holder of any Senior
Indebtedness to enforce subordination as herein provided shall at any time in
any way be prejudiced or impaired by any act or failure to act on the part of
the Company or by any act or failure to act, in good faith, by any such holder,
or by any non-compliance by the Company with the terms, provisions and covenants
of the Subordinated Indenture, regardless of any knowledge thereof any such
holder may have or be otherwise charged with.

               (b) Without in any way limiting the generality of paragraph (a)
of this Section 9, the holders of Senior Indebtedness may, at any time and from
time to time, without the consent of or notice to the Trustee or the holders of
the Securities, without incurring responsibility to the holders of the
Securities and without impairing or releasing the subordination provided in this
Article or the obligations hereunder of the holders of the Subordinated
Indebtedness to the holders of Senior Indebtedness, do any one or more of the
following: (1) change the manner, place or terms of payment or extend the time
or payment of, or renew or alter, Senior Indebtedness or any instrument
evidencing the same or any agreement under which Senior Indebtedness is
outstanding; (2) sell, exchange, 


                                      -10-

release or otherwise deal with any property pledged, mortgaged or otherwise
securing Senior Indebtedness; (3) release any Person liable in any manner for
the collection of Senior Indebtedness; and (4) exercise or refrain from
exercising any rights against the Company or any other Person.


          10. Notice to Trustee

               (a) The Company shall give prompt written notice to the Trustee
of any fact known to the Company which would prohibit the making of any payment
to or by the Trustee in respect of the Securities.  Notwithstanding the
provisions of this Article or any other provision of the Subordinated Indenture,
the Trustee shall not be charged with knowledge of the existence of any facts
which would prohibit the making of any payment to or by the Trustee in respect
of the Securities, unless and until the Trustee shall have received written
notice thereof from the Company or a holder of Senior Indebtedness or from any
trustee, fiduciary or agent therefor; and, prior to the receipt of any such
written notice, the Trustee shall be entitled in all respects to assume that no
such facts, subject to Sections 3.15(a) through 3.15(d) of the Trust Indenture
Act of 1939, exist; provided, however, that, if the Trustee shall not have
received the notice as provided for in this Section 10 at least three Business
Days prior to the date upon which by the terms hereof any money may become
payable for any purpose (including, without limitation, the payment of the
principal of (and premium, if any, on) or interest on any Security), then,
anything herein contained to the contrary notwithstanding, the Trustee shall
have full power and authority to receive such money and to apply the same to the
purpose for which such money was received and shall not be affected by any
notice to the contrary which may be received by it within three Business Days
prior to such date.

               (b) The Trustee shall be entitled to rely on the delivery to it
of a written notice by a Person representing itself to be a holder of Senior
Indebtedness (or a trustee, fiduciary or agent therefor) to establish that such
notice has been given by a holder of Senior Indebtedness (or a trustee,
fiduciary or agent therefor).  In the event that the Trustee determines in good
faith that further evidence is required with respect to the right of any Person
as a holder of Senior Indebtedness to participate in any payment or distribution
pursuant to this Article, the Trustee may request such Person to furnish
evidence to the reasonable satisfaction of the Trustee as to the amount of
Senior Indebtedness held by such Person, the extent to which such Person is
entitled to participate in such payment or distribution and any other facts
pertinent to the rights of such Person under this Article and, if such evidence
is not furnished, the Trustee may defer any payment to such Person pending
judicial determination as to the right of such Person to receive such payment.

in this Article, the Trustee, subject to Sections 3.15(a) through 3.15(d) of the
Trust Indenture Act of 1939, and the holders of the Securities shall be entitled
to rely upon any order or decree entered by any court of competent jurisdiction
in which any insolvency, bankruptcy, receivership, liquidation, reorganization,
dissolution, winding up or similar case or proceeding is pending, or a
certificate of the trustee in bankruptcy, receiver, liquidating trustee,
custodian, assignee for the benefit of creditors, agent or other Person making
such payment or distribution, delivered to the Trustee or to the holders of
Securities, for the purpose of ascertaining the Persons entitled to participate
in such payment or distribution, the holders of Senior Indebtedness and other
Indebtedness of the Company, the amount thereof or payable thereon, the amount
or amounts paid or distributed thereon and all other facts pertinent thereto or
to this Article.


          12. Rights of Trustee As a Holder of Senior Indebtedness;
              Preservation of Trustee's Rights

          The Trustee in its individual capacity shall be entitled to all the
rights set forth in this Article with respect to any Senior Indebtedness which
may at any time be held by it, to the same extent as any other holder of Senior
Indebtedness, and nothing in the Subordinated Indenture shall deprive the
Trustee of any of its rights as such holder.  Nothing in this Article shall
apply to the fees and expenses, and other claims of and payments to, the Trustee
in its capacity as trustee under the Subordinated Indenture.


          13. No Suspension of Remedies.

          Nothing in this Article shall limit the right of the Trustee or the
holders of Securities to take any action to accelerate the maturity of the
Securities or to pursue any rights or remedies hereunder or under applicable
law, provided that the right to receive payment on the Subordinated Indebtedness
is subject to the provisions of Sections 3 and 4.


          14. Trust Moneys Not Subordinated.

          Notwithstanding anything contained herein to the contrary, payments
from cash or the proceeds of U.S. Government Obligations held in trust under the
Subordinated Indenture by the Trustee (or other qualifying trustee) and which
were deposited in accordance with the terms of the Subordinated Indenture and
not in violation of this Article for the payment of principal of (and premium,
if any, on) and interest on the Securities shall not be subordinated to the
prior payment of any Senior Indebtedness or subject to the restrictions set

                                April 21, 1992



Mr. Brian P. Campbell, President
TriMas Corporation
315 E. Eisenhower Parkway
Suite 300
Ann Arbor, Michigan 48180

Dear Brian:

     This will confirm our understanding to modify the Registration Agreement
dated December 27, 1988 among TriMas Corporation, Masco Corporation and Masco
Industries (the "Registration Agreement").  The Registration Agreement
currently limits Masco Corporation and Masco Industries from requesting more
than one registration within a period of twelve months.  At the request of your
underwriters, each of Masco Corporation and Masco Industries agrees that it
will not, for a period of 120 days after the effective date of TriMas'
definitive prospectus relating to its proposed offering of Common Stock,
provided that such effective date is prior to May 15, 1992, (i) offer for sale,
sell, contract to sell or otherwise dispose of any shares of TriMas Common
Stock, or (ii) exercise any Common Stock registration rights granted to each of
them in the Registration Agreement (including but not limited to requesting
registration of shares owned by others).

     In return for the foregoing, and whether or not TriMas' current
registration statement is declared effective, TriMas agrees that the
Registration Agreement is hereby modified so that if Masco Corporation or Masco
Industries requests registration of shares of TriMas Common Stock heretofore
sold to the respective executives of Masco Corporation and Masco Industries
pursuant to the Executive Agreements (as defined below), and such registration
is filed during 1992, they may also request that TriMas file not earlier than
January 1, 1993 a second registration statement covering additional such shares
of TriMas Common Stock heretofore sold pursuant to the Executive Agreements,
even if such second registration is within twelve months of the effective date
of the initial filing during 1992 (so long as such request otherwise complies
with the terms of the Registration Agreement and is made not less than 90 days
from the date of the initial such request).  It is understood that if a
registration request is made in 1992 and the registration statement is for any
reason not filed during 1992, Masco Corporation or Masco Industries shall be
entitled, prior to filing, to increase the number of shares covered by such
request.  All other provisions contained in the Registration Agreement
including but not limited to those limiting registration requests are
unaffected hereby.

<PAGE>   2

     In connection with the foregoing, we advise you as follows:

     1. All executives who have purchased TriMas stock from Masco Corporation
or Masco Industries have done so pursuant to the agreements which shall be
provided to you prior to any request for registration (the "Executive
Agreements").

     2. None of the executives who have purchased TriMas stock pursuant to the
Executive Agreements have notified Masco Corporation or Masco Industries that
they wish to sell any of their TriMas stock in the immediate future.

3. The Executive Agreements currently contain restrictions on sales of stock by
the executive which do not permit the executives to sell in a registered
offering more than 50% of such executive's TriMas stock subject to the
Executive Agreements during 1992, and 75% of such stock by the end of 1993.
Masco Corporation and Masco Industries will not amend, waive or modify the
Executive Agreements to permit any sales in a registered offering in excess of
these restrictions.

     Please confirm TriMas' agreement with the modifications set forth above
which will become effective upon signature as provided below.

     Sincerely,


MASCO CORPORATION                    MASCO INDUSTRIES, INC.

     I acknowledge that the Letter Agreements with each of Masco Corporation

                                                                      CONFORMED



                            STOCK PURCHASE AGREEMENT



     THIS AGREEMENT is made as of this 23rd day of December, 1991 by and
between Masco Corporation, a Delaware corporation ("Masco"), and Masco
Industries, Inc., a Delaware corporation ("Industries").

     Masco and Industries each own one share of the two issued and outstanding
shares of Masco Capital Corporation, a Delaware corporation ("Masco Capital"),
which has been jointly managed by Masco and Industries.  Its most significant
investment was the Junior Subordinated Discount Debentures of Payless Cashways,
Inc. which were recently sold. Related bank loans and indebtedness to the
shareholders have been fully repaid.  Masco Capital has also made a
distribution of its retained earnings.

     Due to Masco Capital's reduced scope, Masco and Industries deem it
appropriate to place the management of Masco Capital under the exclusive
control of Masco.  Further, Industries desires a return of its original capital
investment and to be relieved of the responsibility to provide additional funds
to satisfy its pro rata portion of Masco Capital's future funding obligations.
Accordingly, Industries has agreed to sell and Masco has agreed to purchase
Industries' 50% interest in Masco Capital.  In light of the fact that Masco
Capital's investments generally have no public market, their current value,
which is believed to be in excess of the current book value, is uncertain.  The
parties anticipate that the uncertainty will significantly decrease over the
next three years as the investments are liquidated.  Therefore, the parties
have structured this purchase and sale to pay Industries a small premium over
its current carrying cost of Masco Capital and to provide that Industries will
be in at least as favorable an after-tax financial position at the time of
settlement of obligations as it would have been in if the Masco Capital
investment portfolio were frozen as of December 20, 1991 and then liquidated
over time and the proceeds of the liquidation distributed prior to December 31,
1994.

     NOW, THEREFORE, in consideration of the above premises and the agreements
set forth herein, the parties hereto agree as follows:

     1. Conditions Precedent.  The respective obligations of Masco and
Industries to consummate the transactions contemplated by this Agreement are
subject to (i) the approval on behalf of Masco by the Oversight Committee of
the Masco Board of Directors and (ii) the approval on behalf of Industries by
the Oversight Committee of the Industries Board of Directors.


                                     -1-
<PAGE>   2

     2. Agreement to Purchase and Sell. Subject to the terms and conditions of
this Agreement, Industries agrees to sell, transfer and convey all of its
right, title and interest in and to one share of the capital stock, par value
$1.00 per share, of Masco Capital (the "Masco Capital Share") and Masco agrees
to purchase the Masco Capital Share.

     3. Delivery by Industries.  At the Closing of the transactions
contemplated hereby (the "Closing"), Industries shall deliver to Masco a
certificate representing the Masco Capital Share registered in the name of
Industries and endorsed to Masco Corporation.  The Closing shall be held at the
offices of Masco Capital in Taylor, Michigan on December 30, 1991 at 10:00 a.m.
or at such other time or place as mutually agreed upon by the parties hereto.

     4. Payment.  The aggregate purchase price shall be equal to the sum of (i)
the Closing Price (as hereinafter defined) and (ii) (A) one-half of the
Incremental Value (as hereinafter defined) less (B) $5,200,000, and less (C)
interest on the Closing Price accrued and compounded annually at a rate
equivalent to Masco's average after-tax cost of bank borrowing from the Closing
to the date of payment of such one-half of the Incremental Value; provided,
however, that if Masco has no bank borrowings at a time during the term hereof,
the interest rate during such time shall be the equivalent of an after-tax cost
of 1% under the Prime Rate of NBD Bank, N.A.  The aggregate purchase price
shall be payable as follows:

     (a) The Closing Price shall be $49,451,500 (representing 50% of the Net
Book Value indicated on the balance sheet Masco Capital prepared as of December
20, 1991 and heretofore initialled by the parties plus $5,200,000) and shall be
paid upon the delivery of the Masco Capital Share as provided in Section 3.
For purposes of this Agreement, the term Net Book Value shall mean Total
Shareholders' Equity of Masco Capital without reflecting any write up or write
down in the carrying value of the assets or liabilities of Masco Capital as a
result of a change in the fair market value of such assets or liabilities.

     (b)  Subject to the provisions of Section 10 hereof, the amount determined
under Section 4(ii) shall be paid at the earlier of (i) thirty days after the
date on which the Valuation (as hereinafter defined) is completed but no later
than December 31, 1994 and (ii) thirty days after the date on which the last of
the Investments (as hereinafter defined) shall have been sold, liquidated or
otherwise turned into cash.

     (c) Investments shall mean the investments and assets of Masco Capital
existing on December 20, 1991.

     (d) Incremental Value shall mean the total of:

                                     -2-
<PAGE>   3


           (i)  for Investments that are sold, liquidated or otherwise turned
      into cash, the aggregate of the gain or loss on each such Investment
      determined with reference to the carrying cost of each such Investment;
      plus or minus

           (ii) for Investments which have not been sold, liquidated or
      otherwise turned into cash, and all non-cash proceeds (received or
      receivable) relating thereto, including, without limitation, dividends,
      interest, additional securities and securities derived from such
      Investments by way of reorganization, recapitalization or otherwise (the
      "Proceeds"), the aggregate gain or loss determined with reference to the
      carrying cost of each such Investment and based on a Valuation of such
      Investment (and Proceeds) on September 30, 1994; plus

           (iii) the aggregate of Masco Capital's dividend and interest income
      from (x) the Investments, (y) the Proceeds thereof and (z) cash realized
      on sale, liquidation or otherwise turning into cash of Investments from
      December 20, 1991 until September 30, 1994; minus

           (iv) all management and other fees relating to the Investments paid
      or payable to the investment advisors and managers of the partnerships
      which hold the Investments and all legal, accounting, management and
      other expenses reasonably incurred by Masco Capital relating to
      Investments, in each case from December 20, 1991 until September 30,
      1994; minus

           (v)  all federal, state and local taxes paid or payable on the
      aggregate income from the Investments, including without limitation
      dividends, interest and the gain and loss of such Investments which have
      been sold, liquidated or otherwise turned into cash and an appropriate
      reserve (to be determined by Masco in its sole discretion) to cover all
      such taxes which may be due after September 30, 1994 based on the
      Valuation of all Investments which have not been sold, liquidated or
      otherwise turned into cash at such date.

     (e)  For purposes of this Agreement, Valuation shall mean the value placed
on the Investments (and Proceeds), which have not been sold, liquidated or
otherwise turned into cash on or before September 30, 1994, by the respective
Oversight Committees of the Boards of Directors of Masco and Industries acting
jointly.  However, if such directors do not unanimously agree on such value,
the value of the Investments (and Proceeds) shall be determined by the
valuation department or group of Masco's independent public accountants (which,
unless Masco informs Industries otherwise, shall be Coopers & Lybrand), and the
persons performing the valuation (the "Valuation Group") shall take into
account all relevant business and management considerations using customary
valuation techniques.  If at such time Masco's independent public 

                                     -3-
<PAGE>   4

accountants do not have a valuation department or group, then Masco shall
have the right to select another independent entity to serve as the "Valuation
Group" which, in Masco's reasonable judgment, is experienced and reputable with
respect to such matters.  All determinations by the Valuation Group shall be
final and binding.

     (f)   Masco and Industries acknowledge that the Net Book Value of
$88,503,000 is based on the best information contained in the books and records
of Masco Capital at December 20, 1991.  As soon as practicable after the
Closing (but no later than February 1, 1992) Masco Capital shall prepare a
final balance sheet as of December 20, 1991 based on the books and records of
Masco Capital setting forth an exact Net Book Value and deliver such balance
sheet to Masco and Industries.  If Industries shall not have delivered a
written objection to Masco within 10 business days of receipt of such balance
sheet, such balance sheet will become final.  If the Oversight Committee of the
Industries Board of Directors does deliver a timely written objection with
which Masco does not agree, the balance sheet will be delivered to Coopers &
Lybrand for a final determination of the correct Net Book Value, which shall be
made no later than March 15, 1992.  Upon the final determination of the Net
Book Value on such balance sheet, Masco and Industries shall adjust the Closing
Price based thereon by, (A) if such Net Book Value has increased from
$88,503,000, paying one-half of such increase to Industries in cash within 3
business days of such determination and (B) if such Net Book Value has
decreased, by deducting such decrease from the Incremental Value.  Masco
Capital shall also prepare a definitive list of Investments and the carrying
cost thereof as of the Closing.

     (g) In no event shall the purchase price hereunder be less than the
Closing Price as finally determined pursuant to Section 4(f) hereof.

     5. Subsequent Fundings by Masco.  (a)  If after December 20, 1991 Masco
should provide any additional funds to Masco Capital, Industries shall not
share in any gain or loss resulting from such funds or be paid any amount as
interest, dividends or otherwise relating thereto and any interest expense on
such additional funds shall be disregarded for all purposes hereunder.

     (b)  Notwithstanding the determination of Incremental Value in accordance
with Section 4 hereof, if during the term hereof Masco Capital supplies funds
to a partnership for an investment in an existing Investment and such
additional investment has an impact on the value of the Investment which is
disproportionate to the Investment (as valued by the Oversight Committees
acting jointly at the time of such additional investment) and not reflected in
the value of any security received by Masco in respect of such additional
investment, the Valuation of such Investment (and Proceeds) at September 30,
1994 (or, in the case of an Investment previously sold, liquidated, or
otherwise turned into cash, the amount of gain or loss realized and Proceeds
thereof) shall be 


                                     -4-
<PAGE>   5

equitably adjusted by action of the Committees or, if such
Committees cannot reach unanimous agreement, by the Valuation Group provided in
Section 4(e).

     6. Termination of Fee Agreement.  The Fee Agreement dated as of December
16, 1988 among Masco, Industries and Masco Capital is hereby terminated as of
December 20, 1991 and no liability of any kind will arise to either party from
prior performance or neglect of its terms other than payment of fees up to and
including such  date.

     7.  Payless Preferred Supplier Agreement.  It is Masco's current
intention, so long as Masco is a party to the Supply Agreement dated as of
August 4, 1988 by and between Masco and Payless Cashways, Inc., that Masco
shall continue to designate Industries and its subsidiaries "affiliated
companies" under Article I thereof; provided, however, that Masco is under no
obligation to keep the Supply Agreement in effect, and provided further that
Masco may in its sole discretion terminate such designation at any time upon
reasonable notice.

     8.  Management of Masco Capital.  From the date hereof, Masco shall have
the sole right to manage Masco Capital, make investment decisions and take all
other acts which it may deem necessary or appropriate and Masco shall have no
liability to Industries with respect to such management, investment decisions
or any other matter involving Masco Capital based on action or inaction of
Masco or recklessness, misfeasance, gross negligence or negligence of Masco or
of any of its officers, directors, employees, shareholders or agents in the
handling of Masco Capital's affairs; provided, however, that if Masco is
requested or required by one of the partnerships managing an Investment to make
a decision which may affect the value of such Investment, Masco will notify
Industries before it makes such decision.

     9.  Funding Commitments.  Masco and Masco Capital hereby release
Industries from any and all current or future funding commitments of Masco
Capital which Industries may have or have had with respect to the Investments
or the partnerships holding the Investments or otherwise and Masco agrees to
hold Industries harmless from any loss occasioned by an attempt by any entity
to enforce any such funding commitment.

     10. Termination and Distribution.  (a)  Notwithstanding anything in this
Agreement to the contrary, if the Oversight Committees of the Boards of
Directors of Masco and Industries jointly determine that it is inappropriate to
pay all or part of the Incremental Value based on the Valuation as of September
30, 1994, or if they otherwise jointly determine to defer such Valuation or
payment, then such Committees may in their sole discretion set such payment to
occur in whole or in part after a Valuation on September 30, 1995 or September
30, 1996 and pay only such portion of the Incremental Value prior to December
31, 1994 as 


                                     -5-
<PAGE>   6

such Committees shall jointly determine.  In such case all references to
September 30, 1994 in Section 4 or Section 5 hereof will be deemed to refer to
such later valuation date.

     (b) Notwithstanding anything in this Agreement to the contrary, the
Oversight Committees of the Boards of Directors of Masco and Industries, acting
jointly, may determine following the liquidation of one or more Investments
that it is appropriate for Masco to make a cash payment to Industries prior to
December 31, 1994 (or December 31, 1995 or 1996 as the case may be) as an
advance against amounts that such Committees believe may subsequently be due to
Industries hereunder.  Such advances may be made on such terms (including a
requirement that Industries agree to repay such advance if, after sale,
liquidation or otherwise turning into cash of all Investments, the advance was
not warranted) as such Committees may establish.

     11. Liquidation of Masco Capital.  Nothing in this Agreement shall
preclude Masco from reorganizing, merging, combining or liquidating and winding
up Masco Capital; provided, however, in the event of such a transaction or
series of transactions Masco shall keep separate accounts to enable it to
satisfy its obligations hereunder.

     IN WITNESS WHEREOF, the parties have executed this Agreement as of the
date and year first above written.

INTERNATIONAL, INC., a Delaware corporation (the "Borrower"); CITICORP VENTURE
CAPITAL, LTD., a New York corporation ("CVC") MASCOTECH, INC., a Delaware
corporation ("MascoTech"; and, collectively with CVC and their respective
permitted assignees, the "Bridge Lenders"); and a Bridge Lender or a bank or
other financial institution, in each case designated by the Bridge Lenders and
made a party hereto (in such capacity, the "Administrative Agent") and as
collateral agent (in such capacity, the "Collateral Agent") for the Bridge
Lenders.

          Pursuant to the Acquisition Agreement dated as of November 12, 1996,
as amended (the "Acquisition Agreement"), among the Borrower, MascoTech and MSX
International, Inc., a Michigan corporation ("MSX"), the Borrower will acquire
from MascoTech and MSX, as applicable, directly and through certain
Subsidiaries, the Business (other than certain excluded assets), the APX
Continuing Business, the Limited Stock and the APX- Brazil Stock (as such terms
are defined in the Acquisition Agreement) (collectively, the "Acquisition"), all
for aggregate consideration of approximately $144,628,000, and also consisting
of  the assumption by the Borrower and certain Subsidiaries of certain assumed
liabilities related to the Business and the APX Continuing Business.

          In connection with the Acquisition, CVC and MascoTech, together with
members of management, will make a cash capital contribution to the Borrower in
an aggregate amount of approximately $40 million (the "Equity Contribution").

          The Borrower has requested the Bridge Lenders to extend credit in the
form of (a) bridge term loans on the Closing Date, in an aggregate principal
amount of $40,000,000, and  (b) bridge revolving loans at any time and from time
to time prior to the Final Maturity Date, in an aggregate principal amount at
any time outstanding not in excess of $60,000,000.  The Borrower has requested
MascoTech to arrange for or guarantee the issuance of letters of credit and
other credit facilities to support payment obligations incurred in the ordinary
course of business by the Borrower and the Subsidiaries.

          The proceeds of the Term Loans are to be used, together with a portion
of the proceeds of Revolving Loans to be made on the Closing Date, solely (a) to
pay the cash consideration to be paid in connection with the Acquisition and (b)
to pay related fees and expenses.  The proceeds of the Revolving Loans (other
than the Revolving Loans used for the purposes specified in the immediately
preceding sentence) are to be used for working capital and other general
corporate purposes of the Borrower and the Subsidiaries.

          The Bridge Lenders are willing to extend such credit to the Borrower
on the terms and subject to the conditions set forth herein.  Accordingly, the
parties hereto agree as follows:

          SECTION 2.02 Loans.

          (a) Each Loan shall be made as part of a Borrowing consisting of Loans
made by the Bridge Lenders ratably in accordance with their respective Term Loan
Commitments or Revolving Credit Commitments, as applicable; provided, however,
that the failure of any Bridge Lender to make any Loan shall not in itself
relieve any other Bridge Lender of its obligation to lend hereunder (it being
understood, however, that no Bridge Lender shall be responsible for the failure
of any other Bridge Lender to make any Loan required to be made by such other
Bridge Lender).  The Loans comprising any Borrowing shall be in an aggregate
principal amount that is (i) not less than $5,000,000 and, in each case, in an
integral multiple of $1,000,000 or (ii) equal to the remaining available balance
of the applicable Commitment.

          (b) Each Bridge Lender shall make each Loan to be made by it hereunder
on the proposed date thereof by wire transfer of immediately available funds to
such account in New York City as the Administrative Agent may designate not
later than 12:00 (noon), New York City time, and the Administrative Agent shall
by 1:00 p.m., New York City time, credit the amounts so received to an account
in the name of the Borrower, maintained with the Administrative Agent and
designated in the applicable Borrowing Request or, if a Borrowing shall not
occur on such date because any condition precedent herein specified shall not
have been met, return the amounts so received to the respective Bridge Lenders.

          (c) If a Bridge Lender does not, prior to the date of any Borrowing,
make available to the Administrative Agent such Bridge Lender's portion of such
Borrowing, the Administrative Agent shall not be obligated to  make available to
the Borrower on such date a corresponding amount.

          SECTION 2.03 Borrowing Procedure.  In order to request a Borrowing,
the Borrower shall notify the Administrative Agent by telephone of its intent to
request a Borrowing and shall hand deliver or telecopy to the Administrative
Agent a duly completed Borrowing Request not later than 11:00 a.m., New York
City time, five (5) Business Days before a proposed Borrowing.  Each Borrowing
Request shall be irrevocable, shall be signed by or on behalf of the Borrower
and shall specify the following information:  (i) whether the Borrowing then
being requested is to be a Term Borrowing or a Revolving Credit Borrowing; (ii)
the date of such Borrowing (which shall be a Business Day); (iii) the number and
location of the account to which funds are to be disbursed (which shall be an
account that complies with the requirements of Section 2.02(b)); and (iv) the
amount of such Borrowing; provided, however, that, notwithstanding any contrary
specification in any Borrowing Request, each requested Borrowing shall comply
with the requirements set forth in Section 2.02.  The Administrative Agent shall
promptly advise the applicable Bridge Lenders of any notice given pursuant to
this Section 2.03 (and the contents thereof), and of each Bridge Lender's
portion of the requested Borrowing.

          (a) The Borrower unconditionally promises to pay to the Administrative
Agent for the account of each Bridge Lender (i) the principal amount of each
Term Loan of such Bridge Lender as provided in Section 2.11 and (ii) the then
unpaid principal amount of each Revolving Loan on the Final Maturity Date.

          (b) On the date of any termination or reduction of the Revolving
Credit Commitment pursuant to Section 2.08(b) hereof or elsewhere in this
Agreement, the Borrower shall pay or prepay so much of the Revolving Loans as
shall be necessary in order that the Availability equals or exceeds zero
following such termination or reduction.

          (c) The Borrower shall make prepayments of the Revolving Credit Loans
from time to time such that the Availability equals or exceeds zero at all
times.

          (d) Each Bridge Lender shall maintain an account or accounts
evidencing the Indebtedness of the Borrower to such Bridge Lender resulting from
each Loan made by such Bridge Lender from time to time, including the amounts of
principal and interest payable and paid such Bridge Lender from time to time
under this Agreement.

          (e) The Administrative Agent shall maintain accounts in which it will
record (i) the amount of each Loan made hereunder, (ii) the amount of any
principal or interest due and payable or to become due and payable from the
Borrower to each Bridge Lender hereunder and (iii) the amount of any sum
received by the Administrative Agent hereunder from the Borrower or any
Subsidiary Guarantor and each Bridge Lender's share thereof.  Notwithstanding
any other provision of this Agreement, it is understood and agreed that each
Loan made hereunder shall be deemed made for the account of the Borrower, and
the Administrative Agent and the Bridge Lenders shall not have any obligation to
maintain any accounts with respect to any Borrowing (or any portion thereof)
made by the Borrower.

          (f) The entries made in the accounts maintained pursuant to paragraphs
(b) and (e) above shall be prima facie evidence of the existence and amounts of
the obligations therein recorded; provided, however, that the failure of any
Bridge Lender or the Administrative Agent to maintain such accounts or any error
therein shall not in any manner affect the obligation of the Borrower to repay
the Loans in accordance with their terms.

          (g) Notwithstanding any other provision of this Agreement, in the
event any Bridge Lender shall request and receive a promissory note payable to
such Bridge Lender and its permitted registered assigns, the interests
represented by such note shall at all times  be  represented by one or more
promissory notes payable to the payee named therein or its permitted registered
assigns.

equal to 1.25%, computed on the basis of actual number of days elapsed in a
360-day year.

          (c) All of the above fees shall be paid on the dates due, in
immediately available funds, to the Administrative Agent and Bridge Lenders, as
applicable. Once paid, none of such fees shall be refundable under any
circumstances.

          SECTION 2.06 Interest on Loans.

          (a) Subject to the provisions of Section 2.07, the Loans shall bear

Borrowing.

          (b) Interest on each Loan shall be payable on the Interest Payment
Dates applicable to such Loan except as otherwise provided in this Agreement.
The Loan Rate shall be determined by the Administrative Agent, and such
determination shall be conclusive absent manifest error.

the principal of, or interest on, any Loan or any other amount becoming due
hereunder, by acceleration or otherwise, or under any other Loan Document, the

permitted by law, on such defaulted amount to but excluding the date of actual

amount of $2,000,000 and (ii) the Total Revolving Credit Commitment shall not
be reduced to an amount that is less than the Aggregate Revolving Credit
Exposure at the time.

          (c) Each reduction in the Total Revolving Credit Commitment hereunder
shall be made ratably among the Revolving Credit Lenders in accordance with
their respective Revolving Credit Commitment.

          SECTION 2.09 Repayment of Term Borrowings.

          (a) The Borrower shall pay to the Administrative Agent, for the
account of the Bridge Lenders, on the dates set forth below, or if any such date

<PAGE>   27

          (b)      Optional prepayments of Term Loans shall be allocated pro

          (c)      Each notice of prepayment shall specify the prepayment date

Commitments, the Borrower shall repay or prepay all its outstanding Revolving

Borrower and the Revolving Credit Lenders of the Aggregate Revolving Credit
Exposure after giving effect thereto and (ii) if the Aggregate Revolving Credit
Exposure would exceed the Total Revolving Credit Commitment after giving effect

reduction or termination, repay or prepay Revolving Credit Borrowings in an
amount sufficient to eliminate such excess.

          (b)      Not later than the third Business Day following the receipt

the Net Cash Proceeds received with respect thereto to prepay outstanding Term
Loans in accordance with Section 2.11(f).

          (c)      In the event and on each occasion that an Equity Issuance
occurs, the Borrower shall, substantially simultaneously with (and in any event
not later than the third Business Day next following) the occurrence of such
Equity Issuance, apply 100% of the Net Cash Proceeds therefrom to prepay
outstanding Term Loans in accordance with Section 2.11(f).

          (d)      No later than the earlier of (i) 90 days after the end of
each fiscal year of the Borrower commencing with the fiscal year ending on
December 31, 1997, and (ii) the date on which the financial statements with
respect to such fiscal year are delivered pursuant to Section 5.04(a), the
Borrower shall prepay outstanding Term Loans in accordance with Section 2.11(f)

simultaneously with (and in any event not later than the third Business Day next
following) the receipt of such Net Cash Proceeds by such Loan Party or such
Subsidiary, apply an





                                       22
<PAGE>   28

amount equal to 100% of such Net Cash Proceeds to prepay outstanding Term Loans

          (f)      Subject to paragraph (h) below, mandatory prepayments of
outstanding Term Loans under this Agreement shall be allocated pro rata between
the then outstanding Term Loans, and applied in the inverse order of the
remaining scheduled installments of principal due in respect of Term Loans under
Section 2.09(a).

          (g)      The Borrower shall deliver to the Administrative Agent, at
the time of each prepayment required under this Section 2.11, (i) a certificate
signed by a Financial Officer of the Borrower setting forth in reasonable detail
the calculation of the amount of such prepayment and (ii) to the extent
reasonably practicable, at least three days prior written notice of such
prepayment.  Each notice of prepayment shall specify the prepayment date, the
principal amount of each Loan (or portion thereof) to be prepaid and the amount,
if any, to be deposited in the account or accounts designated by the Bridge
Lenders from time to time.  All prepayments of Borrowings under this Section
2.11 shall be subject to Section 2.11(h) and Section 2.12, but shall otherwise
be without premium or penalty.

          (h)      Amounts to be applied pursuant to this Section 2.11 to the
prepayment of Term Loans and Revolving Loans shall be applied, as applicable,
first to reduce outstanding Term Loans.  Any amounts remaining after each such
application shall, at the option of the Parent  Borrower, be applied to repay
Revolving Loans immediately.

          SECTION 2.12     Pro Rata Treatment.  Each Borrowing, each payment or
prepayment of principal of any Borrowing, each payment of interest on the Loans,
and each reduction of the Revolving Credit Commitments shall be allocated pro
rata among the Bridge Lenders, in the case of principal and interest payments,
in accordance with their respective applicable outstanding Loans and, in the
case of all other payments, the Commitments (or, if such Commitments shall have
expired or been terminated, in accordance with the respective principal amounts
of their outstanding Loans).  Each Bridge Lender agrees that in computing such
Bridge Lender's portion of any Borrowing to be made hereunder, the
Administrative Agent may, in its discretion, round each Bridge Lender's
percentage of such Borrowing to the next higher or lower whole dollar amount.

          SECTION 2.13     Sharing of Setoffs.  Each Bridge Lender agrees that
if it shall, through the exercise of a right of lien, setoff or counterclaim
against the Borrower or any other Loan Party, or pursuant to a secured claim
under Section 506 of Title 11 of the United States Code or other security or
interest arising from, or in lieu of, such secured claim, received by such
Bridge Lender under any applicable bankruptcy, insolvency or other similar law
or otherwise, or by any other means, obtain payment (voluntary or involuntary)
in respect of any Loan or Loans or Additional Credit Disbursement as a result of
which the unpaid principal portion of its Term Loans and Revolving Loans and
participations held by such Bridge Lender in Additional Credit Disbursements
shall be proportionately less than the unpaid principal portion of the Term
Loans and Revolving





                                       23
<PAGE>   29

Loans and participations held by any other Bridge Lender, it shall be deemed
simultaneously to have purchased from such other Bridge Lender at face value,
and shall promptly pay to such other Bridge Lender the purchase price for, a
participation or interest in the Term Loans and Revolving Loans and
participations in Additional Credit Disbursements, as the case may be, of such
other Bridge Lender, so that the aggregate unpaid principal amount of the Term
Loans and Revolving Loans and participations in Additional Credit Disbursements
held by each Bridge Lender shall be in the same proportion to the aggregate
unpaid principal amount of all Term Loans and Revolving Loans and
participations in Additional Credit Disbursements then outstanding as the
principal amount of its Term Loans and Revolving Loans and interests in
Additional Credit Disbursements prior to such exercise of lien, setoff or
counterclaim or other event was to the principal amount of all Term Loans and
Revolving Loans and interests in Additional Credit Disbursements outstanding
prior to such exercise of lien, setoff or counterclaim or other event;
provided, however, that if any such purchase or purchases or adjustments shall
be made pursuant to this Section 2.13 and the payment giving rise thereto shall
thereafter be recovered, such purchase or purchases or adjustments shall be
rescinded to the extent of such recovery and the purchase price or prices or
adjustment restored without interest.  The Borrower expressly consents to the
foregoing arrangements and agrees that any Bridge Lender holding a
participation or interest in a Term Loan or Revolving Loan or Additional Credit
Disbursement deemed to have been so purchased, to the fullest extent provided
by law, may exercise any and all rights of banker's lien, setoff or
counterclaim with respect to any and all moneys owing by the Borrower to such
Bridge Lender by reason thereof as fully as if such Bridge Lender had made a
Loan directly to the Borrower in the amount of such participation.

          SECTION 2.14     Payments.

          (a)      The Borrower shall make each payment (including principal of
or interest on any Borrowing or any Additional Credit Disbursement or any Fees
or other amounts) hereunder and under any other Loan Document not later than
12:00 (noon), New York City time, on the date when due in immediately available
dollars, without setoff or counterclaim.  Each such payment shall be made to
each of the Bridge Lenders, pro rata, or to the Administrative Agent, if any, at
the offices or to the accounts indicated to the Borrower from time to time.

          (b)      Whenever any payment (including principal of or interest on
any Borrowing or any Fees or other amounts) hereunder or under any other Loan
Document shall become due, or otherwise would occur, on a day that is not a
Business Day, such payment may be made on the next succeeding Business Day, and
such extension of time shall in such case be included in the computation of
interest or Fees, if applicable.

          SECTION 2.15     Additional Credit Exposure.

          (a)      Facility.  Masco Tech has prior to the Closing Date, issued
Guarantees and incurred Indebtedness in respect to (i) Designated Guarantee
Obligations and (ii) Designated Letters of Credit identified in Schedule 2.15
hereto, and subject to the terms and conditions and relying upon the
representations and warranties herein set forth, MascoTech may, in its sole
discretion, from time





                                       24
<PAGE>   30

to time issue Guarantees or incur Indebtedness in respect of (x) Designated
Guarantee Obligations and (y) Designated Letters of Credit at any time and from
time to time on and after the Closing Date and until the earlier of the Final
Maturity Date and the termination of the Revolving Credit Commitments in
accordance with the terms hereof, in an aggregate principal amount at any time
outstanding that will not result in the Aggregate Revolving Credit Exposure,
after giving effect to any Additional Credit Exposure, exceeding the Total
Revolving Credit Commitment.

          (b)       Participations.  MascoTech shall give prompt written notice
to the Administrative Agent and each other Revolving Credit Lender of the
occurrence of (a) any Additional Credit Event and (b) any Additional Credit
Disbursement.  Such notice shall specify the aggregate principal or face amount
of the Additional Credit Event in which each such other Revolving Credit Lender
will participate.  On the Closing Date, each other Revolving Credit Lender will
acquire a Pro Rata Percentage participation in all Additional Credit Exposures
identified on Schedule 2.15 hereto.  Automatically and contemporaneously with
each Additional Credit Event occurring on or after the Closing Date, each such
other Revolving Credit Lender will acquire a Pro Rata Percentage participation
in all of the Additional Credit Exposure represented by each Additional Credit
Event.  In furtherance of the foregoing, each such other Revolving Credit Lender
will hereby absolutely and unconditionally agree, upon receipt of notice as
provided above, to pay to the Administrative Agent, for the account of
MascoTech, such other Revolving Credit Lender's Pro Rata Percentage of each
Additional Credit Disbursement.  Each such other Revolving Credit Lender
acknowledges and agrees that its obligation to acquire a participation in each
Additional Credit Exposure pursuant to this paragraph is absolute and
unconditional and shall not be affected by any circumstance whatsoever,
including the occurrence and continuance of a Default or an Event of Default,
and that each payment made in respect of each Additional Credit Disbursement
shall be made without any offset, abatement, withholding or reduction
whatsoever.  Each such other Revolving Credit Lender shall comply with its
obligation under this paragraph by wire transfer of immediately available funds,
in the same manner as provided in Section 2.02(b) with respect to Loans made by
such other Revolving Credit Lender (and Section 2.02(b) shall apply, mutatis
mutandis, to the payment obligations of such other Revolving Credit Lender) and
the Administrative Agent shall promptly pay to MascoTech the amounts so received
by it from such other Revolving Credit Lender.  Any amounts received by
MascoTech from the Borrower (or other party on behalf of the Borrower) in
respect of an Additional Credit Disbursement after receipt by MascoTech of the
proceeds of a sale of participations therein shall be promptly remitted to the
Administrative Agent; any such amounts received by the Administrative Agent
shall be promptly remitted by the Administrative Agent to such other Revolving
Credit Lenders that shall have made their payments pursuant to this paragraph
and to MascoTech, as their interests may appear.  In furtherance of the
foregoing, each such other Revolving Credit Lender agrees that (i) the
Administrative Agent may (y) set off against the fees payable to such Revolving
Credit Lender under Section 2.05(b) such Revolving Credit Lender's Pro Rata
Percentage of the fees paid, and out-of-pocket costs incurred, by MascoTech
pursuant to its Guarantees in respect of Designated Letters of Credit, and (z)
pay such set off amount to MascoTech and (ii) it shall participate in and be
obligated to pay, in accordance with its Pro Rata Percentage, all such fees and
costs to the extent such Revolving Credit lender does not fully pay its Pro Rata
Percentage of such fees and costs pursuant to clause (i) above.

                         Representations and Warranties

          The Borrower represents and warrants to the Bridge Lenders that:

          SECTION 3.01      Organization; Powers.  Each of the Borrower and the
Subsidiaries (a) is a corporation duly organized, validly existing and in good

and each other agreement or instrument contemplated hereby to which it is or
will be a party and, in the case of the Borrower, to borrow hereunder, except in
each case where the failure to satisfy any of the above could not reasonably be
expected to result in a Material Adverse Effect.

          SECTION 3.02      Authorization.  The execution, delivery and
performance by each Loan Party of each of the Loan Documents to which such Loan
Party is a party, and in the case of the Borrower, the borrowings hereunder and

where any such conflict, violation, breach, default or right referred to in
clause (i) or (ii), individually or in the aggregate, could not reasonably be
expected to have a Material Adverse Effect, or (iii) result in the creation or
imposition of any Lien upon or with respect to any property or assets now owned
or hereafter acquired by the Borrower or any Subsidiary (other than any Lien
created hereunder or under the Security Documents).

          SECTION 3.03      Enforceability.  This Agreement has been duly
executed and delivered by the Borrower and constitutes, and each other Loan
Document when executed and delivered by each Loan Party thereto will constitute,
a legal, valid and binding obligation of such Loan Party enforceable against
such Loan Party in accordance with its respective terms, subject (a) as to

<PAGE>   32

other similar laws affecting the enforcement of creditors' rights generally,
from time to time in effect and (b) to general principles of equity (whether
enforcement is sought by a proceeding in equity or at law) .

          SECTION 3.04      Governmental Approvals.  No action, consent or
approval of, registration or filing with or any other action by any Governmental

material adverse change in the business, assets, operations, properties,
financial condition, contingent liabilities or material agreements of MSX and/or

such terms are defined in the Acquisition Agreement).

          SECTION 3.06      Title to Properties; Possession Under Leases.

          (a)      Each of the Borrower and the Subsidiaries has good title to
(and with respect to real property good and marketable title to), or valid
leasehold interests in, all its material properties and assets (including all
properties listed on Schedule 3.16(b)), except where lack of such title or valid
leasehold interest does not materially interfere with its ability to conduct its
business as currently conducted.  All interests of such persons in such material
properties and assets are free and clear of Liens, other than Liens expressly
permitted by Section 6.02.

          (b)      Except as set forth on Schedule 3.06(b), each of the Borrower
and the Subsidiaries has complied with all material obligations under all
material leases to which it is a party and all such leases are in full force and

undisturbed possession under all such material leases, except where failure to
enjoy such possession does not materially interfere with its ability to conduct
its business as currently conducted.

          SECTION 3.07      Subsidiaries.

          (a)      Schedule 3.07 sets forth as of the Closing Date (after giving

fully paid and nonassessable and are owned, as of the Closing Date, by the
Borrower or a subsidiary of the Borrower, as applicable, directly or indirectly,
free and clear of all Liens (other than Liens permitted under the Loan

Subsidiary Guarantor.

          (b)      As of the Closing Date, except as set forth in Schedule 3.07,
none of the Subsidiaries is subject to a consensual encumbrance or restriction
that limits such Subsidiary's ability to make an Upstream Payment.

          SECTION 3.08      Litigation; Compliance with Laws.

          (a)      Except as set forth on Schedule 3.08, there are no actions,
suits or proceedings at law or in equity or by or before any Governmental
Authority now pending or, to the knowledge of the Borrower, threatened against
or affecting the Borrower or any Subsidiary or any business, property or rights
of any such person (i) that involve any Loan Document or the Transactions or
(ii) as to which there is a reasonable likelihood of an adverse determination
and that could reasonably be expected, individually or in the aggregate, to
result in a Material Adverse Effect.

          (b)      None of the Borrower or any of the Subsidiaries or any of
their respective material properties or assets is in violation of, nor will the
continued operation of their material properties and assets as currently
conducted violate, any law, rule or regulation (including any zoning, building,
Environmental Law, ordinance, code or approval or any building permits), or is

any Governmental Authority, where such violation or default could reasonably be
expected to result in a Material Adverse Effect.

of the Loans only for the purposes specified in the preamble to this Agreement.
No part of the proceeds of the Loans will be used directly or indirectly for any
purpose which would violate or be inconsistent with Regulations G, T or X of the
Board of Governors of the Federal System of the United States of America.

          SECTION 3.10     Tax Returns.  Each of the Borrower and the
Subsidiaries has filed or caused to be filed all Federal, state or other
material tax returns required to have been filed by it and has paid or caused to
be paid all taxes due and payable by it and all assessments received by it to
the extent that such failure to file or nonpayment could reasonably be expected
to result in a Material Adverse Effect.

          SECTION 3.11     No Material Misstatements.  None of the information,
reports, financial statements, exhibits or schedules, taken as a whole,
furnished by or on behalf of the Borrower to the Administrative Agent or any
Bridge Lender in connection with the negotiation of any Loan Document or
included therein or delivered pursuant thereto contained, contains or will
contain any material misstatement of fact or omitted, omits or will omit to
state any material fact necessary to make the statements therein, in the light
of the circumstances under which they were, are or will be made, not materially
misleading, provided that to the extent any such information, report, financial
statement, exhibit or schedule was based upon or constitutes a forecast or
projection,





                                       28

the Borrower represents only that it acted in good faith and utilized
reasonable assumptions and due care in the preparation of such information,
report, financial statement, exhibit or schedule.

          SECTION 3.12     Employee Benefit Plans.  Except to the extent failure
to comply could not reasonably be expected to result in a Material Adverse
Effect, each of the Borrower and the Subsidiaries is in compliance with the
applicable provisions of ERISA and the Code and the regulations and published
interpretations thereunder.  The Borrower is not aware of any circumstances or
event with respect to any employee benefit plan maintained or contributed to by
an ERISA Affiliate that could result in a liability that could reasonably be
expected to have a Material Adverse Effect.  No ERISA Event has occurred or is

result in a Material Adverse Effect;

Subsidiaries are in compliance, and in the last three years have been in
compliance, with all Environmental Laws and all necessary Environmental Permits

non-compliance or failure to obtain any necessary permits, in the aggregate,
could not be reasonably expected to result in a Material Adverse Effect.

          (c)      There have been no Releases or threatened Releases at, from,
under or proximate to the Properties or otherwise in connection with the
operations of the Borrower or the Subsidiaries, which Releases or threatened
Releases, in the aggregate, could reasonably be expected to result in a Material
Adverse Effect.

          (d)      None of the Borrower or any of the Subsidiaries has received
any notice of an Environmental Claim in connection with the Properties or the
operations of the Borrower or the Subsidiaries or with regard to any person
whose liabilities for environmental matters the Borrower or the Subsidiaries has
retained or assumed, in whole or in part, contractually, by operation of law or
otherwise, which, in the aggregate, could reasonably be expected to result in a
Material Adverse Effect; and

          (e)      Hazardous Materials have not been transported from the
Properties, nor have Hazardous Materials been generated, treated, stored or
disposed of at, on or under any of the Properties in a manner that could

                                       29
<PAGE>   35
contractually, by operation of law or otherwise, with respect to the
generation, treatment, storage or disposal of Hazardous Materials, in each
case, which transportation, generation, treatment, storage or disposal, or
retained or assumed liabilities, in the aggregate, could reasonably be expected
to result in a Material Adverse Effect.

          SECTION 3.14     Insurance.  As of the date hereof and the Closing
Date, all insurance maintained by the Borrower and the Subsidiaries is in full
force and effect and all premiums that have become due and payable have been

covering such risks and liabilities as are in accordance with normal industry
practice.

          SECTION 3.15     Security Documents.

          (a)      The Pledge Agreement is effective to create in favor of the
Collateral Agent, for the ratable benefit of the Secured Parties, a legal, valid
and enforceable security interest in the Collateral (as defined in the Pledge
Agreement) and, when such Collateral is delivered to the Collateral Agent, the
Pledge Agreement shall constitute a fully perfected first priority Lien on, and

in such Collateral, in each case prior and superior in right to any other
person.

          (b)      The Security Agreement is effective to create in favor of the

in the Security Agreement) that may be perfected by filing, recording or
registering a financing statement under the Uniform Commercial Code as in effect
in the United States (or any political subdivision thereof) and its territories
and possessions, in each case prior and superior in right to any other Lien on
any Collateral other than Liens expressly permitted by Section 6.02.

lock-outs, work stoppages or slowdowns presently

being made, undertaken or, to the knowledge of the Borrower or any Subsidiary,
threatened involving any employees of the Borrower or any Subsidiary.  The
hours worked by and payments made to employees of the Borrower and the
Subsidiaries have not been in violation of the Fair Labor Standards Act or any
other applicable Federal, state, local or foreign law dealing with such matters
in any case where a Material Adverse Effect could reasonably be expected to
occur as a result of such violations.  The consummation of the Transactions
will not give rise to any right of termination or right of renegotiation on the
part of any union under any collective bargaining agreement to which the
Borrower or any Subsidiary is bound.

cause to be made, all needful and proper repairs, renewals, additions,
improvements and replacements thereto necessary in order that the business
carried on in connection therewith may be properly conducted in all material
respects at all times.

<PAGE>   40
     
          (i)      none of the Collateral Agent or any Bridge Lender, or their
     respective agents or employees shall be liable for any loss or damage
     insured by the insurance policies required to be maintained under this
     Section 5.02, it being understood that (A) the  Borrower and the other
     Loan Parties shall look solely to their insurance companies or any other
     parties other than the aforesaid parties for the recovery of such loss or
     damage and (B) the Borrower shall use reasonable efforts to cause such
     insurance policies to waive the insurer's rights of subrogation against
     the Collateral Agent and the Bridge Lenders or their agents or employees. 
     If, however, any such insurance policy does not provide waiver of
     subrogation rights against such parties, as required above, then the
     Borrower hereby agrees, to the extent permitted by law, to waive its right
     of recovery, if any, against the Collateral Agent and the Bridge Lenders
     and their agents and employees in respect of any such loss or damage; and

          (ii)     the designation of any form, type or amount of insurance
     coverage by the Collateral Agent under this Section 5.02 shall in no event
     be deemed a representation, warranty or advice by the Collateral Agent that
     such insurance is adequate for the purposes of the business of the Borrower
     and the Subsidiaries or the protection of their properties.

property, before such taxes, assessments and governmental charges shall become
delinquent or in default, as well as all lawful claims for labor, materials and
supplies or otherwise that, if unpaid, might give rise to a Lien upon such
properties or any part thereof; provided, however, that such payment and
discharge shall not be required with respect to (i) any such tax, assessment,
charge, levy or claim so long as the validity or amount thereof shall be
contested in good faith by appropriate proceedings and the Borrower shall have
set aside on its books adequate reserves with respect thereto in accordance with
GAAP and such contest operates to suspend collection of the contested
obligation, tax, assessment or charge and enforcement of a Lien and (ii) any
Indebtedness or other obligation or any tax, assessment, charge, levy or claims,
the failure to pay and discharge when due which, individually or in the
aggregate, could not reasonably be expected to have a Material Adverse Effect.

          SECTION 5.04      Financial Statements, Reports, etc.  Furnish to each

Bridge Lenders and accompanied by an opinion of such accountants (which shall

               The Administrative Agent and the Collateral Agent

          In order to expedite the transactions contemplated by this Agreement,
a Bridge Lender or a bank or other financial institution, in each case
designated by the Bridge Lenders and made a party hereto, shall be appointed to
act as Administrative Agent and Collateral Agent on behalf of the Bridge Lenders
(for purposes of this Article VIII, the Administrative Agent and the Collateral
Agent are referred to collectively as the "Agents").  Each of the Bridge Lenders
and each assignee of any such Bridge Lender, hereby irrevocably authorizes the
Agents to take such actions on behalf of such Bridge Lender or assignee and to
exercise such powers as are specifically delegated to the Agents by the terms
and provisions hereof and of the other Loan Documents, together with such
actions and powers as are reasonably incidental thereto.  The Administrative
Agent is hereby expressly authorized by the Bridge Lenders, without hereby
limiting any implied authority, (a) to receive on behalf of the Bridge Lenders
payments of principal of and interest on the Loans and all other amounts due to
the Bridge Lenders hereunder (other than payments that are specifically
required to be paid directly to a Bridge Lender), and promptly to distribute to
each Bridge Lender its proper share of each payment so received; (b) to give
notice on behalf of each of the Bridge Lenders to the Borrower of any Event of
Default specified in this Agreement of which the Administrative Agent has
actual knowledge acquired in connection with its agency hereunder; and (c) to
distribute to each Bridge Lender copies of all notices, financial statements
and other materials delivered by any Loan Party pursuant to this Agreement or
the other Loan Documents as received by the Administrative Agent.  Without
limiting the generality of the foregoing, the Agents are hereby expressly
authorized to execute any and all documents (including releases) with respect 
to the Collateral and the rights of the Secured Parties with respect thereto, as
contemplated by and in accordance with the provisions of this Agreement and the
Security Documents.

          Neither the Agents nor any of their respective directors, officers,
employees or agents shall be liable as such for any action taken or omitted by
any of them except for its or his own gross negligence or wilful misconduct, or
be responsible for any statement, warranty or representation herein or the
contents of any document delivered in connection herewith, or be required to
ascertain or to make any inquiry concerning the performance or observance by any
Loan Party of any of the terms, conditions, covenants or agreements contained in
any Loan Document.  The Agents shall not be responsible to the Bridge Lenders
for the due execution, genuineness, validity, enforceability or effectiveness of
this Agreement or any other Loan Documents, instruments or agreements.  The
Agents shall in all cases be fully protected in acting, or refraining from
acting, in accordance with written instructions signed by the Required Bridge
Lenders and, except as otherwise specifically provided herein, such instructions
and any action or inaction pursuant thereto shall be binding on all the Bridge
Lenders.  Each Agent shall, in the absence of knowledge to the contrary, be
entitled to rely on any instrument or document believed by it in good faith to
be genuine and correct and to have been signed or sent by the proper person or
persons.  Neither the Agents nor any of their respective directors, officers,
employees or agents shall have any responsibility to any Loan Party on account
of the failure of or delay in performance or breach by any Bridge Lender of any
of its 


                                     51


<PAGE>   57

obligations hereunder or to any Bridge Lender on account of the failure
of or delay in performance or breach by any other Bridge Lender or the Borrower
or any other Loan Party of any of their respective obligations hereunder or
under any other Loan Document or in connection herewith or therewith.  Each of
the Agents may execute any and all duties hereunder by or through agents or
employees and shall be entitled to rely upon the advice of legal counsel
selected by it with respect to all matters arising hereunder and shall not be
liable for any action taken or suffered in good faith by it in accordance with
the advice of such counsel.

          If any Administrative Agent and Collateral Agent is appointed after
the date of this Agreement, it shall, as a condition to its appointment, enter
into a joinder agreement with, upon such terms as are acceptable to, the parties
hereto and become a party to this Agreement and the Loan Documents.

          The Bridge Lenders hereby acknowledge that neither Agent shall be
under any duty to take any discretionary action permitted to be taken by it
pursuant to the provisions of this Agreement unless it shall be requested in
writing to do so by the Required Bridge Lenders.

          Subject to the appointment and acceptance of a successor Agent as
provided below, either Agent may resign at any time by notifying the Bridge
Lenders and the Borrower.  Upon any such resignation, the Required Bridge
Lenders shall have the right to appoint a successor, provided that such
appointment shall require the consent of the Borrower (which consent shall not
be unreasonably withheld), so long as no Default or Event of Default shall have
occurred and be continuing.  If no successor shall have been so appointed by the
Required Bridge Lenders and shall have accepted such appointment within 30 days
after the retiring Agent gives notice of its resignation, then the retiring
Agent may, on behalf of the Bridge Lenders, appoint a successor Agent which
shall be a bank with an office in New York, New York, or Detroit, Michigan,
having a combined capital and surplus of at least $500,000,000.  Upon the
acceptance of any appointment as Agent hereunder by a successor bank, such
successor shall succeed to and become vested with all the rights, powers,
privileges and duties of the retiring Agent and the retiring Agent shall be
discharged from its duties and obligations hereunder.  After the Agent's
resignation hereunder, the provisions of this Article and Section 9.05 shall
continue in effect for its benefit in respect of any actions taken or omitted to
be taken by it while it was acting as Agent.

          With respect to the Loans made by it hereunder, each Agent in its
individual capacity and not as Agent shall have the same rights and powers as
any other Bridge Lender and may exercise the same as though it were not an
Agent, and the Agents and their Affiliates may accept deposits from, lend money
to and generally engage in any kind of business with, the Borrower or any
Subsidiary or other Affiliate thereof as if it were not an Agent.

          Each Bridge Lender agrees (a) to reimburse the Agents, on demand, in
the amount of its pro rata share (based on its Commitments hereunder, or if such
Commitments have expired or been terminated, based on its outstanding Loans) of
any expenses incurred for the benefit of the Bridge Lenders by the Agents,
including counsel fees and compensation of agents and employees 

                                     52

paid for services rendered on behalf of the Bridge Lenders, that are required
to be but shall not have been reimbursed by the Borrower and (b) to indemnify
and hold harmless each Agent and any of its directors, officers, employees or
agents, on demand, in the amount of such pro rata share, from and against any
and all liabilities, taxes, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind or nature
whatsoever that may be imposed on, incurred by or asserted against it in its
capacity as Agent or any of them in any way relating to or arising out of this
Agreement or any other Loan Document or any action taken or omitted by it or
any of them under this Agreement or any other Loan Document, to the extent the
same are required to be but shall not have been reimbursed by the Borrower or
any other Loan Party, provided that no Bridge Lender shall be liable to an
Agent or any such other indemnified  person for any portion of such
liabilities, obligations, losses, damages,  penalties, actions, judgments,
suits, costs, expenses or disbursements that  resulted from the gross
negligence or wilful misconduct of such Agent or any of its directors,
officers, employees or agents. 

          Each Bridge Lender acknowledges that it has, independently and without
reliance upon the Agents or any other Bridge Lender and based on such documents
and information as it has deemed appropriate, made its own credit analysis and
decision to enter into this Agreement.  Each Bridge Lender also acknowledges
that it will, independently and without reliance upon the Agents or any other
Bridge Lender and based on such documents and information as it shall from time
to time deem appropriate, continue to make its own decisions in taking or not
taking action under or based upon this Agreement or any other Loan Document, any
related agreement or any document furnished hereunder or thereunder.

representations and warranties made by the Borrower herein and in the
certificates or other instruments prepared or delivered in connection with or
pursuant to this Agreement or any other Loan Document shall be considered to
have been relied upon by the Bridge Lenders shall survive the making by the
Bridge Lenders of the Loans, regardless of any investigation made by the Bridge
Lenders on their behalf, and shall continue in full force and effect as long as
the principal of or any accrued interest on any Loan or any Fee or any other
amount payable under this Agreement or any other Loan Document is outstanding
and unpaid and so long as the Commitments have not been terminated.  The
provisions of Sections 9.05 and 9.15 shall remain operative and in full force
and effect regardless of the expiration of the term of this Agreement, the
consummation of the transactions contemplated hereby, the repayment of any of
the Loans, the expiration of the Commitments, the invalidity or
unenforceability of any term or provision of this Agreement or any other Loan
Document, or any investigation made by or on behalf of the Administrative
Agent, the Collateral Agent or any Bridge Lender. 

          SECTION 9.03      Binding Effect.  This Agreement shall become
effective when it shall have been executed by the Borrower and the
Administrative Agent and when the Administrative Agent shall have received
counterparts hereof which, when taken together, bear the signatures of each of

benefit of the parties hereto and their respective permitted successors and
assigns.

          SECTION 9.04      Successors and Assigns.

          (a)      Whenever in this Agreement any of the parties hereto is

behalf of the Borrower, the Administrative Agent or the Bridge Lenders that are
contained in this Agreement shall bind and inure to the benefit of their
respective successors and assigns.

          (b)      Each Bridge Lender may assign to one or more assignees all or
a portion of its interests, rights and obligations under this Agreement
(including all or a portion of its Commitment and the Loans at the time owing to
it); provided, however, that except in the case of an assignment to a Bridge
Lender or, in the case of CVC, to 399 Venture Partners Inc., the other Bridge
Lenders must give their prior written consent to such assignment (which consent
shall not be unreasonably withheld), and the parties to each such assignment
shall execute and deliver to the Administrative Agent an Assignment and
Acceptance in the form attached hereto as Exhibit F (the "Assignment and
Acceptance").

                                     54


<PAGE>   60

          (c)      The Administrative Agent shall maintain at one of its offices
in The City of New York a copy of each Assignment and Acceptance delivered to it
and a register for the recordation of the names and addresses of the Bridge
Lenders, and the Commitments of, and principal amount of the Loans owing to,
each Bridge Lender pursuant to the terms hereof from time to time (the
"Register").  The entries in the Register shall be conclusive and the Loan
Parties, the Administrative Agent, the Collateral Agent and the Bridge Lenders
shall treat each person whose name is recorded in the Register pursuant to the
terms hereof as a Bridge Lender hereunder for all purposes of this Agreement,
notwithstanding notice to the contrary.  The Register shall be available for
inspection by the Loan Parties, the Collateral Agent and any Bridge Lender, at
any reasonable time and from time to time upon reasonable prior notice. 

          (d)      Any Bridge Lender may, in connection with any assignment or
proposed assignment pursuant to this Section 9.04, disclose to the assignee or
proposed assignee any information relating to the Borrower furnished to such
Bridge Lender by or on behalf of the Borrower provided that, prior to any such
disclosure of information, each such assignee or proposed assignee shall execute
an agreement in the form of Exhibit G.

          (e)      Neither the Borrower nor any other Loan Party shall assign or
delegate any of its rights or duties hereunder without the prior written consent
of each Bridge Lender, and any attempted assignment without such consent shall
be null and void.

          SECTION 9.05      Expenses; Indemnity.

          (a)      The Borrower agrees to pay all reasonable out-of-pocket
expenses incurred by the Administrative Agent, the Collateral Agent and the
Bridge Lenders in connection with the preparation and administration of this
Agreement and the other Loan Documents or in connection with any amendments,
modifications or waivers of the provisions hereof or thereof or incurred by the
Administrative Agent, the Collateral Agent or any Bridge Lender in connection
with the enforcement or protection of its rights in connection with this
Agreement and the other Loan Documents or in connection with the Loans made
hereunder, including the reasonable fees, charges and disbursements of counsel
for the Administrative Agent and the Collateral Agent, and, in connection with
any such enforcement or protection, the reasonable fees, charges and
disbursements of any other counsel for the Administrative Agent, the Collateral
Agent or any Bridge Lender.

          (b)      The Borrower agrees to indemnify the Administrative Agent,
the Collateral Agent and each Bridge Lender, each Affiliate of any of the
foregoing persons and each of their respective directors, trustees, officers,
employees and agents (each such person being called an "Indemnitee") against,
and to hold each Indemnitee harmless from, any and all losses, claims, damages,
liabilities and related expenses, including reasonable counsel fees, charges and
disbursements, incurred by or asserted against any lndemnitee arising out of, in
any way connected with, or as a result of (i) any claim, litigation,
investigation or proceeding, whether or not any Indemnitee is a party thereto,
relating to the execution or delivery of this Agreement or any other Loan
Document or any agreement or instrument contemplated thereby, the performance by
the 

                                     55

<PAGE>   61

parties thereto of their respective obligations thereunder, the consummation
of the Transactions and the other transactions contemplated thereby or the use
of the proceeds of the Loans or (ii) any actual or alleged presence or Release
of Hazardous Materials on any property owned or operated by the Borrower or any
of the Subsidiaries, or any Environmental Claim related in any way to the
Borrower or the Subsidiaries;  provided that such indemnity shall not, as to any
Indemnitee, be available to the extent that such losses, claims, damages,
liabilities or related expenses are determined by a court of competent
jurisdiction by final and nonappealable judgment to have resulted from the gross
negligence or wilful misconduct of such Indemnitee.

          (c)      The provisions of this Section 9.05 shall remain operative
and in full force and effect regardless of the expiration of the term of this
Agreement, the consummation of the transactions contemplated hereby, the
repayment of any of the Loans, the expiration of the Commitments, the invalidity
or unenforceability of any term or provision of this Agreement or any other Loan
Document, or any investigation made by or on behalf of the Administrative Agent,
the Collateral Agent or any Bridge Lender.  All amounts due under this Section
9.05 shall be payable on written demand therefor.

          SECTION 9.06      Applicable Law.  THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS (OTHER THAN AS EXPRESSLY SET FORTH IN OTHER LOAN DOCUMENTS) SHALL BE
CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK.

          SECTION 9.07      Waivers; Amendment.

          (a)      No failure or delay of the Administrative Agent, the
Collateral Agent or any Bridge Lender in exercising any power or right hereunder
or under any other Loan Document shall operate as a waiver thereof, nor shall
any single or partial exercise of any such right or power, or any abandonment or
discontinuance of steps to enforce such a right or power, preclude any other or
further exercise thereof or the exercise of any other right or power.  The
rights and remedies of the Administrative Agent or the Collateral Agent and the
Bridge Lenders hereunder and under the other Loan Documents are cumulative and
are not exclusive of any rights or remedies that they would otherwise have.  No
waiver of any provision of this Agreement or any other Loan Document or consent
to any departure by any Loan Party therefrom shall in any event be effective
unless the same shall be permitted by paragraph (b) below, and then such waiver
or consent shall be effective only in the specific instance and for the purpose
for which given.  No notice or demand on the Borrower in any case shall entitle
the Borrower to any other or further notice or demand in similar or other
circumstances.

          (b)      Neither this Agreement nor any provision hereof may be
waived, amended or modified except pursuant to an agreement or agreements in
writing entered into by the Borrower and the Required Bridge Lenders.

          SECTION 9.8      Interest Rate Limitation.  Notwithstanding anything
herein to the contrary, if at any time the interest rate applicable to any Loan
or participation in any Additional Credit Disbursement, together with all fees,
charges and other amounts which are treated as interest or loan charges on such
Loan under applicable law (collectively the "Charges"), shall exceed the maximum
lawful rate (the "Maximum Rate") which may be contracted for, charged, taken,
received or reserved by the Bridge Lender holding such Loan or participation in
accordance with applicable law, the rate of interest payable in respect of such
Loan or participation hereunder, together with all Charges payable in respect
thereof, shall be limited to the Maximum Rate and, to the extent lawful, the
interest and Charges that would have been payable in respect of such Loan or
participation but were not payable as a result of the operation of this Section
9.09 shall be cumulated and the interest and Charges payable to such Bridge
Lender in respect of other Loans or participations or periods shall be
increased (but not above the Maximum Rate therefor) until such cumulated
amount, together with interest thereon at the Prime Rate to the date of
repayment, shall have been received by such Bridge Lender.

          SECTION 9.09      Entire Agreement.  This Agreement, the other Loan
Documents and the confidentiality agreements previously signed by the Bridge
Lenders constitute the entire contract between the parties relative to the
subject matter hereof.  Any other previous agreement among the parties with
respect to the subject matter hereof is superseded by this Agreement and the
other Loan Documents.  Nothing in this Agreement or in the other Loan Documents,
expressed or implied, is intended to confer upon any party other than the
parties hereto and thereto any rights, remedies, obligations or liabilities
under or by reason of this Agreement or the other Loan Documents.

          SECTION 9.10     WAIVER OF JURY TRIAL.  EACH PARTY HERETO HEREBY
WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE
TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING
OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY OF THE OTHER LOAN
DOCUMENTS.  EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR
ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH
OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING
WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN
INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS, AS
APPLICABLE, BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN
THIS SECTION 9.10.

          SECTION 9.11     Severability.  In the event any one or more of the
provisions contained in this Agreement or in any other Loan Document should be
held invalid, illegal or unenforceable in any respect, the validity, legality
and enforceability of the remaining provisions contained herein and therein
shall not in any way be affected or impaired thereby (it being understood that
the invalidity of a particular provision in a particular jurisdiction shall not
in and of itself affect the validity of such provision in any other
jurisdiction).  The parties shall endeavor in 

                                     57


<PAGE>   63

good-faith negotiations to replace the invalid, illegal or unenforceable
provisions with valid provisions the economic effect of which comes as close as
possible to that of the invalid, illegal or unenforceable provisions.

          SECTION 9.12     Counterparts.  This Agreement may be executed in
counterparts (and by different parties hereto on different counterparts), each
of which shall constitute an original but all of which when taken together shall
constitute a single contract, and shall become effective as provided in Section
9.03.  Delivery of an executed signature page to this Agreement by facsimile
transmission shall be as effective as delivery of a manually signed counterpart
of this Agreement.

          SECTION 9.13     Headings.  Article and Section headings and the Table
of Contents used herein are for convenience of reference only, are not part of
this Agreement and are not to affect the construction of, or to be taken into
consideration in interpreting, this Agreement.

          SECTION 9.14     Consent to Service of Process.

          Each party to this Agreement irrevocably consents to service of
process in the manner provided for notices in Section 9.01.  Nothing in this
Agreement will affect the right of any party to this Agreement to serve process
in any other manner permitted by law.

          SECTION 9.15     Confidentiality. The Administrative Agent, the
Collateral Agent and each of the Bridge Lenders agrees to keep confidential and
not to publish, disclose or otherwise divulge (and to cause its respective
officers, directors, employees, agents and representatives to keep confidential
and not publish, disclose or otherwise divulge) the Information (as defined
below), except that the Administrative Agent, the Collateral Agent or any Bridge
Lender shall be permitted to disclose Information (a) to such of its respective
officers, directors, employees, agents, affiliates and representatives
(including counsel) as need to know such Information (who will be informed of
the confidential nature of the Information), (b) to the extent otherwise
required by applicable laws and regulations or by any subpoena or similar legal
process, or requested by any regulatory authority (in any which event notice
thereof will be provided to the Borrower and the applicable party to the extent
not prohibited by applicable law), (c) in connection with any suit, action or
proceeding relating to the enforcement of its rights hereunder or under the
other Loan Documents or (d) to the extent such Information (i) becomes publicly
available other than as a result of a breach of this Section 9.15 or (ii)
becomes available, or was available, to the Administrative Agent, any Bridge
Lender or the Collateral Agent on a nonconfidential basis from a source other
than the Borrower or any of its affiliates and such source is not bound by a
confidentiality agreement to the Borrower and is not otherwise prohibited from
transmitting the information to a third party.  For the purposes of this
Section, the term "Information" shall mean all financial statements,
certificates, reports, agreements and information (including all analyses,
compilations and studies prepared by the Administrative Agent, the Collateral
Agent or any Bridge Lender based on any of the foregoing) that are received from
the Borrower or any of its affiliates or representatives and related to the
Borrower or any of its affiliates, any shareholder of the Borrower or any
employee, 

                                     58

<PAGE>   64

customer or supplier of the Borrower or any of its affiliates, other
than any of the foregoing that were available to the Administrative Agent, the
Collateral Agent or any Bridge Lender on a nonconfidential basis prior to its
disclosure thereto by the Borrower.  The provisions of this Section 9.15 shall
remain operative and in full force and effect regardless of the expiration and
term of this Agreement.

(1) The effect of options and warrants conversions in 1994 would be
    anti-dilutive.
(2) The effect of preferred stock conversions in 1996, 1995 and 1994 would be
    anti-dilutive.
(3) The results of assumed conversion of convertible debentures and preferred
    stock in 1996 are anti-dilutive and therefore are excluded. Amounts for 1995
    and 1994 agree to primary earnings (loss) per common share amounts since the
    results of assumed conversion of securities are anti-dilutive.
